You can apply it to the back or both sides if you want. Or... undercoat or seal the back to stop future rust. It's all up to you and what you think will stop the rust. Personally, I think drainage of the inside of the panel is huge. If it can drain and stay dry in there, you're gold :)

What grit did you use on the da sander we always like to know the grits you use its important good video thanks

[@LakesideAutobody]

For DA sanding around your body work, it's very common to start with 120 grit or even old 40 grit on a bondo hog to knock the grinder marks down fast. Then move to 220-240 further out and scuff even further to make sure you don't get primer on shiny paint. This is what body shops use - internet, TV, etc. will probably say finer grit. For speed and production though start with a course grit and move to finer - much faster and less materials being wasted.

[@vincemajestyk9497]

Nice repair! I used to do these kind of repairs all the time when I was a teenager (before I had a welder) or for my daily drivers. Sometimes if the hole wasn't too big I would ding in the hole and use Tigerhair strand filler under then regular on top.

Putting the fiberglass over bare metal will the metal underneath rust? How long does a repair like that usually last?

[@LakesideAutobody]

As long as the panel can drain and dry out inside, there's no telling how long it will last. Basically if it stays dry - forever. That being said, I usually get quite a few years out of a decent repair - like over 5 easily - again as long as the panel can drain and stay somewhat dry inside :)

I have went through three auto body schools. This fix is only good if you can get behind it to put a water barrier behind it. Another new product on the market is panel adhesive and a piece of metal over the spot. The issue with that is feathering which 9 times out of 10 the eye will not see if you you are a little high. Cutting the metal out and butt welding is the only way to make good as new.

Thank you for your informative videos. I watched this one and another you made, concerning using fiberglass as an alternative to welding. I might mention that I had a problem. I used regular filler after the fiberglass application and the glass at the ends of the patch popped through my primer. I know I used resin to smooth it all but after sanding it down, I had this issue. In your other video, there was a small segment where you mentioned Bondo Glass. I ground off my filler and bought some of this and it seems to be working. All that said, did I do something wrong?

[@LakesideAutobody]

Sorry - I was not able to get to your first post on this for some reason. When you sand your fiberglass, you'll want to make sure the edges are smooth and "feathered" into the metal. Your filler should also feather into the metal. Everything should be smooth when you spray your primer surfacer. Make sure you use "High Build" primer surfacer (Urethane Primer Surfacer or Lacquer Primer Surfacer) as this has thickness which covers up the bodywork imperfections. You will then block sand this and it will be perfect. Here's a video on block sanding: kzbin.info/www/bejne/e4LQon6egdCYhbM Hope this answers you ? - if not ask again - Jerry

[@williamwest5827]

You do fine body work. However, I was wondering if you could apply less body filler, as it seems after looking at numerous videos from Lakeside auto body quite a bit of filler is applied and 80- 90% or so of it is then removed. Looks like extra work but you are the expert. Thank you for all the tips and techniques!

[@LakesideAutobody]

When I worked I was on commission so I try to get it in one shot. A lot of guys would wipe a thin layer, sand, spread another layer, sand, etc. I don't mind wasting the filler as it is pretty cheap - 19/gal . You can do it both ways - it's up to the individual. Both ways have the same longevity. Good question William :)

[@rodparnell1953]

What do you recommend as a sealer for behind the repair to help keep the moisture out and prolong its life?

[@LakesideAutobody]

First allow for drainage - any way you can. That's the most important thing. The panel must be able to dry out inside. Second, if you can get to the back side - sand blast it real quick or at least clean it and use some good 3M or similar undercoating to seal the repair. Last, I swear by this - new or old repaired cars - kzbin.info/www/bejne/r2GYlYGuqZKhjMU

[@donaldappelhof2059]

Does it last? Does it hold up?

[@LakesideAutobody]

It will hold up really well if you can undercoat the back side - if not, it depends on a lot of stuff like water, salt, winters etc. But to be totally honest, if you drive it in the winter and salt, I'd say about three years and you'll begin to see some return of rust of bubbling of the paint.

[@robertrpenny]

Nice job and it might be less likely to rust again than a metal patch.

[@LakesideAutobody]

Thanks Robert - with proper drainage so that no debris can build up inside the panel, it can last quite a long time. If never driven in the winter, it will last 10+ or more years with ease :)

[@ThatZombieDude]

For grinding bare metal (40 grit fiber disc) For sanding bondo (always 40 to start then 80 to finish) For blockiing primer (80, 120, or 150) - 80 for real big stuff. For finish sanding primer 220, 320, or 400 wet sand. For color or clear paint sanding before buffing (800-1500) - your choice. That's it - hope that helps - Jerry

@@LakesideAutobody Thank you for replying. I have a nice 69 Firebird but my 15 year old daughter wanted a C10. The bed has some small homes above the wheel well. Perhaps I’ll try the fiberglass if the rust isn’t too bad. She’ll be a new driver so I don’t want the truck to be concourse quality. Just want it to look decent. We can always really restore it down the road if she doesn’t get into an accident. Thanks again for your help. I live in Connecticut. What state is your shop in?

[@nihilisticpunk24]

What brand fiberglass cloth/filler do you recommend? I know most people think its a deal sin to use anything with 'bondo' written on it.

[@LakesideAutobody]

Any brand fiberglass cloth will work. Don't listen to the chatter or the internet,TV or magazines about bondo products. They are all fine - the filler, the reinforced filler, red lacquer glazing putty, fiberglass resin, cloth, etc. "bondo" got it's bad name from folks that used the products in the wrong way - applying them incorrectly.

[@nickking1510]

@@LakesideAutobody 100% agree . Many should never touch their cars ever lololol. Especially lazy people body work is hard work and attention to detail bond aka plastic fill epoxy and fibreglass are excellent for repairs providing it’s prepped correctly .

Quick question, Jerry . Is smc fiber glass resin. The same as polyester, fiberglass resin.. I am working on a truck semi are accordingly is made out of SMC if you used the polyester fiberglass Resin and creates a reaction, causing the repair to fail. Is this a myth buster? Are they making pay more or it’s true

[@LakesideAutobody]

SMC is a combination of glass-fiber and polyester material molded into panels using a compression process. Fiberglass is glass strands that are woven into cloth and layered using polyester resin. They are close but not exactly the same animal. That being said, I have fixed SMC panels using old fashioned fiberglass and fiberglass resin and it holds up well. Here's an example - kzbin.info/www/bejne/mmi7e4CimZmWg7s Like anything though, it's always best to go with the correct products and procedures. I like the question and am writing that down. Good topic for a myth buster type video. Hope that helps a bit :)

Love the video what size sanding paper your using on both Sanders and where did you get the cheese grader from

[@LakesideAutobody]

Cheese grater is from Amazon, 40 grit to start with on the filler, 80 grit to finish the filler, 120 grit to DA with or feather edge, scuff with 3M scuff pad any shiny paint you might get primer on and then prime - glad you like the video

[@Plyley1961]

Nice video and helpful. This will work well to patch a small spot on my 2000 Wrangler rocker panel before I put the rocker panel guards on. Thanks for going through the steps of using the fiberglass first, then how to apply the body filler.

You're welcome - glad you appreciate it

[@davekana8388]

So do you recommend taking off the fender? What grit paper on the bondo hog and DA? Thanks, Dave

[@LakesideAutobody]

It's not necessary but it could help when trying to undercoat the back. Even w/o undercoating the back it should hold up well as long as you have drain holes or a way that salt water and debris can escape.

[@davekana8388]

Lakeside Autobody, what grit paper are you using on the bondo hog and DA, thanks, Dave!

[@shirazvadia]

Hi wont the rust around the place u fibreglassed start again.

[@LakesideAutobody]

In a few years you'll probably have a bit of bubbling if you drive it in salt water. If you coat the backside or allow it to drain and dry by drilling holes in the bottom of the fender, it can last much longer. Remember.... no moisture = no rust.

[@shirazvadia]

Another awesome video Lakeside. Well done. 😁👍🏻👍🏻 How long could you expect a repair like this to last you think?

Years if there is good drainage so the inside can drain and dry out - free of debris, leaves, needles, etc. Here's a follow up video on same repair - neighbors truck (still fine today) - kzbin.info/www/bejne/qmK6lJ-KlKyArM0

Hey Lakeside, do you happen to have a video that covers cutting out a section of a “replacement panel” to fit a section that you have removed, say of course due to rust, & you’re trying to get your replacement piece to fit as “perfectly” as possible before welding it in?? Thanks buddy!!

[@playsportfun3356]

What about all the rust on the back side?

[@LakesideAutobody]

What I usually do for welding a patch is cut all the bad metal out. If you could coat the back side with something that would definitely help.

[@johnbeer5242]

🙄

[@billjones5178]

What does DA sanding do? What grit? Can I do that by hand on one job for me? I have no DA sander?

[@LakesideAutobody]

It basically feather edges the paint - makes a smooth transition from the thickness of the paint to the metal. Yes you can do it by hand. Start with 80 grit and move to 120 then 220 - prime - then paint.

[@maurizioalfieri602]

Someone says that fiberglass/metal joint can't last for a long time due to different temperature expansion between materials. How true is that?

[@LakesideAutobody]

Not true at all. I think if the metal was like 10 feet long there may be enough expansion to cause problems but with small distances, you are probably talking about a fraction of a hair which is about .0001" or most likely none at all. Here's proof - The lower passenger fender of this truck was done the exact same way about 2 years ago :)

[@gary24752]

Has it lasted or did the rust come back and mess it up?

[@LakesideAutobody]

This will not last as long as welded patch panels or panel adhesive - but it is an accepted auto body repair in the industry. Without protection on the back - you'll probably get 2-3 years out of it before seeing the rust start to push the filler away from the metal. However, if you sand blast or sand and seal the back with rubberized undercoating or something similar and allow for drainage, it will last forever really as there's no way for moisture to affect the patched area.

[@slimeade6021]

I got rockers going out on my car. After I clean up the rust there will probably be 6” x 3” hole. How would I shape the fiberglass in my case since the hole is much larger than the one in this video?

[@crpth1]

The easiest way to cover larger areas. Is to use a "form" . By form read anything that can temporarily hold the desired shape until it dry enough to self support. All is fair game. Metal mesh, aluminum or stainless steel work quite well. So does wax paper, plastic bags, cardboard, duct tape... BTW duct tape is perfect to hold plastic or paper in place. Depending on resin type, material, thickness, hardner, etc. We might be talking about 10 minutes to overnight. So your "form" is a very temporary need. After a single layer of cloth, others can be added later. Bridging a hole can be a minutes thing! ;-)

[@claybird8184]

What do you think about por15 and fiberglass cloth? Softball size hole on my truck was patched with fiberglass and it shrunk and pulled away, I have no idea how they did it though. Thanks!!

[@LakesideAutobody]

Here's how they did it - kzbin.info/www/bejne/an3HiXmsmd-GetU If you do it like my video, it will last a long time especially if you can seal the back side of it with a really good undercoating - even roof tar. I know that sounds crazy but you want something that doesn't flake off. Something that stays flexible and gooey on the back to seal it off from salt water.

[@peterjlindley]

You want to use a rust converter on the back or it will continue to rust and your repair will fall out. Then you can undercoat over the rust converter.

[@LakesideAutobody]

@@peterjlindley On the back of the repair?

[@peterjlindley]

@@LakesideAutobody Yes. If it was rusted on the front, it will be rusted behind. Rust converter will convert any of that rust and will stop the rusting process. Even when you grind off rust it is hard to get it all and even a small amount will continue rusting. You could use some POR15 if you can get access to the back of the repaired panel.

[@LakesideAutobody]

@@peterjlindley I know this sounds crazy but In Canada they give the underside of cars oil baths. After some time it gets like an old valve cover and doesn't rust. I personally make sure pinch welds (bottoms of doors, deck lids, hoods etc) are coated with used motor oil. I'm always looking for ideas to coat the back side of repairs - even using roof tar or something that stays gooey but is cheap. Any ideas? Jerry

[@alexiooambiza1806]

Can I ask wat is the name of that tool u are using to grand the body filler

Do you find that a fiberglass repair under filler will last any shorter or longer than say welding a new piece of steel in?

[@FIGGY65]

Get some paint sticks that fit across the span of the rear of the hole, and put magnets on the ends of the sticks. Lay the sticks from behind and perhaps place foil or wax paper between the fiberglass and the wood sticks to keep the resin from bonding to them. I only saw this today, so my apologies for being late!

[@johnsteed265]

@@FIGGY65 I use spray foam in a can. Spray the foam in the hole, let dry, sand it down, fiberglass then putty. Beautiful every time and it lasts for years!

[@nickking1510]

You can use cardboard with a sheet of wax paper over it and place the cardboard on the inside of the repair once it’s hard remove the cardboard and wax paper once the repair is completed and paint is cured apply some oil behind the repair and then brush on some asphalt black undercoat working it into the oiled metal and fibreglass so water and dampness and salt can’t soak into repair don’t skip the oiling trust me 50 years experience it works . The Encapsulates only cover rust I don’t use then on old metal , they would be fine on brand new car/truck under wheel wells and frames floors but won’t stop inner frame rust or seam or weld rust

[@carmo9693]

How long does this type of repair last for. I always thought when metal is rotted out like that you had to cut it out so it doesn't continue to rot out, even if it was sand blasted?

[@LakesideAutobody]

If you seal both sides it will last forever (well almost). If you don't seal the back or at least give the water and moisture a way to drain out - you're right it will return. The rate depends on how often it's driven in salt and moisture. If it's a trailer queen it will again last forever :)
