Episode 70 Part 2 Seamless floor pan installation, 1965--70 Mustang, Autorestomod

[@AutoRestoMod]

We have always cut out what was rusty, trimmed the panel down to a too large a size (covers the hole) and used spray paint (or weldable primer) to mark the exact dimensions of the patch then cut the new metal to size. We hen used welding magnets to hold the new panel to the old panel and started welding...wow, that typed out so much easier than it is to do...

[@stevenwolfe7615]

Great job Gary 👍

[@AutoRestoMod]

POR15 will get down in any voids on the welding inside the cab and keep the panel nice and clean. Welds also tend to rust more readily than plain sheet metal. We are also using the POR 15 on areas that had light rust on them.

[@electricguysvcs]

I like all that fireproof cardboard.

[@mrossett60]

Gary is an artist!

[@AutoRestoMod]

Yeah, he has used that set up for a long while Aaron with good success.

[@robbys67rs]

[@jwilson6086]

Great video. Very informative. Its definitely a video I'm going to watch a lot when I finally get to doing my floors in my grand wagoneer.

[@sirranger7713]

Thank you so much. You are making my life a smooth ride

[@AutoRestoMod]

Thanks for the kind words. Plug welding is the best way to keep heat and warping down so we do recommend doing that all the way around.

[@alldabeanzracing9650]

I'm not an expert, but I think you guys have your terminology wrong? The plug welds is where he welded the pieces together through the drilled out holes. Then he butt welded the seam of the over lapping panels with a series of tack welds.

[@AutoRestoMod]

Yes. They will use that for tight areas.

[@AutoRestoMod]

Our best advice is to go to a welding supply shop and talk to a rep. You CAN get a cheap welder and deal with epic frustration or spend a bit of money on a beginner Miller or Lincoln and have a welder that will last you years with good service. A rep (a good one) will show you what you need.

[@Grey-Fox_94]

Impressive end result.

[@gpierce01]

I needed to see this! Great educational video. Thanks guys!

[@cecil6711]

Nice repair and looks undetectable from underneath.

[@AutoRestoMod]

Well normally we would do that sort of thing on a full bore restoration. But this car is complete and a cruise-in car and we don't want to rip into it that deeply. We wanted to show that a repair like this could be done without tearing the whole interior out.

[@AutoRestoMod]

Well, we have used the Lizard Skin with great success on two or three projects. We've also used Dynamat--it just depends on the application. Keep in mind that Lizard Skin is not truck bed liner, this product is military spec and a variation of it is used by the armed forces for the same things we use it for.

[@vcval]

I have only removed lead so far but what I have learnt is the youtube videos are more informative then the Dvd from eastwoods but is good to watch anyway just for research

[@AutoRestoMod]

The primer will act as a rust preventative until we can get to the Lizard Skin sound deadener. The Lizard Skin will effectively seal the pan.

[@guillermonieri4203]

Very useful info. Thank you.

[@sanchtech]

Gary is a good welder.

[@Wormanager]

Brilliantly done!

[@AutoRestoMod]

We might do a leading video some day but so far our experience with the stuff has been mixed. One side of the '67 looks great and the other needs to be redone...That lets us know it isn't the product it is the operator.

[@AutoRestoMod]

Yep, Body Schutz. This is if it is NOT a Concours car. The factory only used Schutz in certain areas. Be sure to consult assembly manuals for your model for instructions on Schutz locations if you are doing a Concours car.

[@jknighthomes]

keep it up guys. this is my fave youtube channel. Gonna look through your videos to find a two point seatbelt installation video for my 61 tbird....I can't figure out where to drill!

[@shamnampatandy]

Use of spray paint to mark the butt weld edge - genius. I've been struggling with a Sharpie :-s

[@AutoRestoMod]

Wow, the Sharpe has it's place in auto-body but no there. Yeah that one had us saying the same thing.

[@AutoRestoMod]

Welding creates sparks that can damage the headliner, carpet, seats and dash. The cardboard keeps the sparks from getting on these areas and damaging them.

[@InvincibleExtremes]

Cool video. Liked it

[@sheriesanta4432]

cool show, thanks for the info

[@AutoRestoMod]

Original Parts Group carries some stuff for the Monte, try them.

[@AutoRestoMod]

LOL yes. Gary doesn't believe in wasting consumables. Where we would have pitched it the guys at Mustang Central use everything to within an inch of it's life... or less in the case of the cut off wheels.

[@ztwntyn8]

great vid. I primer then seam seal though. no need to use filler, it's covered will promote rust and crack. my. I think they used an undercoating though before the seam sealer so I should look into that as well. some undercoatings won't let things adhere so it's likely a rust proofing that promotes adhesion. like they say hammer every weld and get those seems close it a must. pro work here. I also dig the cardboard everywhere possible. thumb up

[@AutoRestoMod]

Get a copy of HP books Welding and check on what wire size you should use. But yes the Flux Core should work famously. Do your self a favor and get some scrap in the same gauge metal as your floors and practice. The repops can get expensive.

[@DudeDudesson]

OK, thank’s for your answer. I take it as, the method saves time, but there is no disadvantage to welding edge-to-edge.

[@AutoRestoMod]

No none at all. On a Camaro there is no frame rail like those on a Mustang and so that time savings goes out the window.

[@LAKERAT_YT]

Lol yall wanna come to Michigan and do my floor pans in my 67 falcon awesone job!

[@AutoRestoMod]

I haven't gotten over doing the floors in the Ranchero yet...

[@aaroncake]

A few coats of POR-15 under the car instead of the filler will not only fill in the weld/grinding roughness, but won't absorb water like the glazing compound nor flake off in a few years after being battered by road debris. I'm actually quite amazed that a professional would advocate using filler on the bottom of a vehicle. Has he tested his method long term in real world weather?

[@aaahhhh00]

safety tip: when grinding fiber glass or other debris areas, the paper mask will not stop particles, you will need a more serious respirator that stops debris, like an asbestos mask 30$ from home depot , each cartridge is only good for about 12- 20 hours of continuous use then they need to be replaced.you dont want this stuff in your lungs. happy grinding.

[@minyoungc_]

When using those self tapping screws to hold the floorpan in place while you weld, do you remove them at the end and then weld the holes left behind?

[@TheHamadanners]

awsome. learn quiet a bit i took a two year course buuit they never covered floor pans.

[@1DjYo]

great video! helped me a lot. I need to weld in a floor pan and i want to do it myself. what is a good and inexpensive welding torch i could get?

[@Dnrice]

Did you take out the screws or leave them in?

[@AutoRestoMod]

Took them out and welded the holes. Sorry that wasn't as clear as it should have been.

[@AutoRestoMod]

Monte Enlacalle, According to Jeff, Mustang Central charges around $1,100 for a set of floor pans. But you should contact them to be sure; Jeff's memory ain't what it used to be...

[@GratefulMeds]

do you think raptor liner is the same thing as lizard skin. and why do you use that over some of the other liner type products.

[@Satdvr27]

You mentioned you were doing a butt joint weld. Sure that wasn't a lap joint weld? Look like some overlap to me. could be deceptive though. Thanks for the video.

[@AutoRestoMod]

Gary did a butt joint (wow the comedy potential of that two word group is nearly endless) on the rear section at the seat pan and a lap at the firewall/toe board just like the factory did.

[@sanchtech]

Is that a flap disk on the porter cable angle grinder?

[@fordchevinman4614]

Hi was the self taping screws removed or welded over? I'm new at this

[@AutoRestoMod]

After we finished welding toward those screws we removed them and welded the holes up.

@@AutoRestoMod thanks, great video, I'm currently welding some some small patches on my camaro.

[@SUBJ3CT_M4YH3M]

Hi Jeff, I noticed at the end of the install that Gary was putting what looked like a seam sealer on the drain hole cover. I assumed that a drain hole cover would need the ability to be removed, so what's the best thing to do? Just seam seal all drain hole covers? I'm also asking since I've got to conduct the exact same repair, but on the drivers side instead. The original panel doesn't have a drain hole in it, but the new panel does. Also still loving the videos, very entertaining and informative. So keep up the GR8 Work!!!

[@AutoRestoMod]

1484Youngy we use sealer, either strip calk or gun applied. Ford usually drizzled brushable sealer on them. Thanks for the kind words about the show, we could not do this without you!

[@robbiegwinn]

awsome vid.....ty

[@DudeDudesson]

Just watched this video after having done the exact same thing on my 69 Camaro. To my surprise you are not welding edge-to-edge. I always do that to make the repair absolutely invisible, without filler. Is there a reason for not welding edge-to-edge, other than that it takes a few more hours to do?

[@AutoRestoMod]

Dude, We actually did butt weld the rear of the floor pan and the exposed areas. The frame rail, toe board, and cross members weren't butt welded because it does save time, is just as strong and no one will see the repair unless they pull the carpet.

[@ELPATRON839]

What about the last piece Gary was putting on what did he apply on that hole an what was that gray stuff he used

[@AutoRestoMod]

+Ayy gee Uprising It was a self leveling seam sealer. Basically any good quality seam sealer will work.

[@OriginalCaptainHowdy]

Why would you use PaintOverRust15? You have nice clean metal, sand it with 80g and spray a good epoxy primer on it.

[@oreokookie1000]

Great professional job...wonder, tho.....I notice he welded from underneath the car, but later put a bead of caulk on the unwelded edge on the floor....why not weld the top side? Then caulk the under- car seam?? Confused here...I have a pan job coming up.

[@PeytonGregory]

it looks like he what he was welding underneath wasn't accessible from the top. He's welding the lip where the vise grips are clamped at 7:06

[@BU1Robertson]

I have floor two half pans and a rear seat pan that needs installed. Not having much luck finding someone willing to do the work. Any tips?

[@AutoRestoMod]

We'd recommend hitting the car shows locally. find out from the folks in your area who does the best work for the best price.

[@ShazamBoom]

Hi, thanks for the great videos. Beginning at 6:44, you mention that it's better to plug weld the floor pan into place, as opposed to a continuous stitch weld. Do you plug weld it all around? Or is there also continuous butt welding involved? I also noticed a sheet metal overlap where the new pan meets the old by the tunnel. Thanks!

[@tspecht610]

I am curious about how come you overlapped the pan on the top side near the hump instead of just seam sealing it if you want to make it appear that it was never repaired? I have a 1970 and have liked your videos and am trying to learn what is the best way to do all of these things to have the top quality car.

[@AutoRestoMod]

We only lapped in places where there was a cross brace.

[@doriethpalma1964]

What's the specs on the welder that you used

[@stevemills6473]

what does the underside of the car look like after the welds? How do you ensure that moisture won't get inside the overlap?

[@AutoRestoMod]

He used a weldable primer that will probably out last the rest of the car.

[@alldabeanzracing9650]

Probably i will never understand why, when u have a full replacement panel available in your hands and nice shop with all the tools in the world to do a nice job, u still cut, fit and play all day, destroying the brand new panel to do this kind of job... instead of replace the whole thing and make it legit and right from the first time ..... Please correct me if im wrong...

[@MrJaespun]

T. F. A wise body man once told me to never cut more then what’s needed & keep car as original as possible.

[@maintayne]

I'm watching this video to find the answer to this very question. I have an entire floor pan but only the low spots maybe 30% of the floor is rusty. Should I replace the entire panel or just the bad areas?

[@markalexander6185]

Hello T.F. These guys are HACKS!!!!!....NONE of their combined Excuses are Justifiable!!!....HACKS are HACKS!!!...Mark

[@corneleousworthington4566]

I think it's to keep the car with as much original metal as possible. Although with my fox body mustang I had so much rust that I just used the whole replacement panels

[@2010invent]

@@maintayne Do the hole panel. "If you have rust here, you will have it everywhere but you will only see it when your foot goes though it". That is an ancient Chines proverb.

[@scottgerke976]

If I'm doing this job on a daily driver, do I still need to do all that body filler work underneath? Are there any steps I can skip to save some money but not compromise the longevity?

[@AndrewMiguelez]

You don't need to do anything, but every little bit helps. Keep in mind that every seam, edge, and hole underneath is prone to attract and hold water. So the smoother it is, the less likely you'll see rust forming any time soon. And definitely don't skip the painting step! Bare metal is a huge no-no.

[@ldnwholesale8552]

No, that is purely finish. Seam sealer on both side will suffice. just not as neat. I have done that job a few times and the panels never seemed to fit as well so lots of seam sealer!! I bet Garry has done that quite a few times and practice makes perfect.

[@dstonz]

Pretty much how I do it. I use Metal to Metal most of the time instead of the fiberglass. Using hammers as panel holder downers must be employed when doing this type repair lol. And here I thought I was the only one smart enough to use the light to find small holes. I tell people to fill the car up with water and plug the leaks. I am so mean.

[@vcval]

i thought the plug hole was going the be leaded in got a little excited :(, great job though from underneath looks like you were never there :)

[@yamarr1981]

Hi, just out of curiosity, what’s the grey finish on the bottom of the pan in the end?

[@AutoRestoMod]

That is epoxy primer. Gary then sprayed (at our request) black semi-gloss paint.

[@SpXzDIff]

Did you lift the car off the chassis? Did you remove all the gas lines, and gas tank? I got a 66 impala that need floor pans welded in..

[@AutoRestoMod]

Ford the gas line runs down the drivers side. Had we been working over there we would have removed the lines and capped the end on the tank line with a rubber plug. Gas fumes are more dangerous than the liquid. Lifting the body off the frame is a tough job. We'd probably try and fix it with the frame in place. BUT if you can't access a weld point you'll need to pop that body off...

[@jenniesboy]

just a random question. in your opinion would a flux core welder work for floor pans? i have a 1989 K1500 chevy. its in dire need for floor pans/cab corners and im wanting to go buy a welder but the only one currently in my budget is a flux core only type welder. I have heard that if you take your time and jump around the panel it would produce the same finish as a mig or what have you. any advice would be great. work time is not a issue as for i have years to work on it.

[@aaahhhh00]

hello Dustin, I purchased the harbor freight flux core thinking id be able to do these type of repairs, and there just isn't enough flexibility with the unit to spot weld these thin gauge body panels you end up either blowing right through ( too much heat) or not getting enough penetration ( to short of time with the weld machine activated), a friend had to come and use his Hobart and then his miller either mig is optimal, and a must in my opinion, don't waste your time and money as harbor freight wont reimburse you for there machine. get a quality unit and start practicing on the same gauge metal.

[@nathanbrown5833]

why r u lap welding? is that proper way to get things done?

[@AutoRestoMod]

Depends on what you are looking for. Keep in mind that most of the car has sheet metal that is spot-welded to each other and has no rust inhibitor between the sheets. That lasts a long time. They use a weldable primer that helps to inhibit rust and the parts are e-coated.

[@stevemills6473]

OH, I see it now...so you still have to weld on the BOTTOM of the panel, too!

[@MissionRestomod]

Using a combustible material (cardboard) to protect the interior while welding...

[@MissionRestomod]

A good depiction of how someone might do it at home. That is a stitch weld btw. A spot weld uses... a spot welder. I think you meant full, continuous seam weld.

[@AutoRestoMod]

From Jeff: Well, I've set my pant leg on some ratty blue jeans on fire before with a stick welder, but I've never set cardboard on fire with welding spark; but now that I said that... BUT technically you are correct. One should use welding blankets, welding jacket, welding gloves and a beanie (welding) hat.

[@AutoRestoMod]

Sorry sometimes in the heat of battle we use wrong words. =)

[@radioguy1620]

personally I'd rather have an overlap , seems it would be much stronger as the weld would be brittle, to help prevent this problem I next got a cowl cover off ebay the magnetic ones work easy and never blew off even roadracing my 66

[@AutoRestoMod]

Yeah, that would work; though the lap weld is not really going to be any stronger or weaker than a well done butt weld. Our problem on that car was oddly not the cowls, it was the fact that the radio areal grommet was not plugged in and water got into the interior.
