For someone less experienced with sanding (like me), it helps to spray a layer of darker color primer then a layer of lighter color primer, to help see high and low spots for more sanding and priming. Project Farm KZbin videos test maintenance products for vehicles.

How times have changed. When I was coming up in the 70s the idea was to use very little if any monkey hair, Bondo on a repair. All the fillers are Petrie dishes for cracks, paint peeling etc. unused auto paint was used for high spots. My time came right after the use of lead. Those men were truly talented. Sucks to get old, revolving cycle. Peace

All those old guys in the 50's 60's and 70's were very talented. Brick layers, masons, plaster, draftsmen, builders, body men, on and on..... It's amazing that all that knowledge disappears when the guy passes away - sad really. Peace to you too my friend :)

[@Okie-Tom]

Good video. One thing you didn't mention was that the bondoglass and kitty hair, being a fiberglass based filler , is that it is waterproof, unlike regular bondo which soaks up water. The fiberglass keeps any moisture away from the problem area! Also, I would like to see photos of the rack you were using here. Take care. Tom

[@LakesideAutobody]

The rack that I'm using is just two big triangles made of 2x4's. I just C clamp them to the car lift ramps and attach the various panels any safe way that I can - but I'll try to get a video on that for you - Thanks for watching :)

[@MrTheHillfolk]

My question, is it still polyester based ? If so ,it's the same as bondo with all the moisture absorption that comes with it. Epoxy based is a different story. Fiberglass boats gain weight sitting in the water,tells me right there that polyester isnt all it's cracked up to be.

[@natevanlandingham1945]

​@@MrTheHillfolkit's not the fiberglass that absorbs water it's them leaking from somewhere and the wood and foam that they use in them that gain the weight.

[@MrTheHillfolk]

[@natevanlandingham1945]

@@MrTheHillfolk I own several boats. One is fiberglass. I have owned two other fiberglass boats as well. They have a gelcoat on the outside of them, they should not have water penetrating the hull..if there is you have a leak. If you have a leak your foam flotation in the bilge and the wood will absorb it. Never glass constructed boats use plastic wood or basically it's like those plastic cutting boards you use in the kitchen. It's called like HTPE plastic or something?

[@DavidGuns]

I know this video is 2 years old, my question is why would you use a rubber undercoating? Living in Chicago the rustbelt once a tiny drop of water gets under the undercoating it starts to rust. Been doing body and paint for over 34 years, I mainly work on vintage and classic cars. I do leading which you know is a dying art, but one of the best repairs. I was lucky enough to start in a shop when I was 19 and was getting trained, one day I was watching the owner do some lead work on his I think it was a 46 Oldsmobile. I was just amazed how the lead just flowed. I asked the owner if he could teach me and it was the best thing I ever learned.

[@LakesideAutobody]

You are absolutely right - we've all experienced what Ziebart causes. It does have it's place though if you really clean the back side a prep it well - it'll last quite a while. I prefer this though to any other method of prevention - kzbin.info/www/bejne/bonEi3WvbKx2baM or this kzbin.info/www/bejne/r2GYlYGuqZKhjMU Hope that clears things up - thanks for watching my friend :)

I did many repairs using Tiger Hair etc. back in the 70s and early 80s before I could afford my first MIG welder. In High School and the few years following we all had rust buckets and some of us knew how to fix them. I got so I could even repair shapes like the dog leg part of the rear door jamb. I had a cheap sandblaster to blow the rust away, then used Tiger Hair. I would knock the metal down a bit, put a coat of Tiger Hair on, then embed a piece of fiberglass cloth saturated with Tiger Hair over that. Lay a piece of wax paper from the kitchen over it so I could press the cloth into the Tiger Hair and mold it all into shape and flatten the lumps out as it hardened. Top it with a skim of Bondo, seal the back with undercoat and these repairs would last for several years.

Can you paint over the bondo glass with Por 15 or do you have to prime first. I have pin holes in my VW bug and I hit it with ospho and now getting ready to tackle the pin holes

[@LakesideAutobody]

It's normal practice to prime over it first. You can use any type of automotive grade primer though - lacquer, epoxy, or urethane. Epoxy doesn't sand well so if you are going to block sand the first application of primer it's best to go with lacquer primer surfacer or urethane primer surfacer. Or even some spray bomb primer if you're just doing a daily driver.

[@drywaller12345]

A question...you used the electric sander at the beginning as opposed to DA Sander,,?? why so ?? Thanks

[@LakesideAutobody]

That was a grinder/sander/buffer with a 40 grit fiber resin disc on it to remove the paint and really rough up the metal in order for the filler to stick really well. Filler never peels, chips or fall off of a properly prepared surface. You can use a DA too but sometimes a DA is not fast enough for me and it doesn't stay as sharp as the 40 grit fiber resin disc - instead of cutting it rubs if dull and filler don't like to stick well to that :)

[@C0Y0TE5]

What is the secret to not getting 40 grit sand marks in the metal not to show after painting? When I used to do body work even after heavy priming it seemed like the scratches in the metal always showed.

[@LakesideAutobody]

The ones in the metal never show for me (there's really no scratches or "deep" scratches. If I leave them in the paint (don't DA or feather edge well) they end up showing (sometimes). Sometimes you can get away with cheating a bit. If you leave your filler a bit full and sand the rest with 80 grit (what your supposed to do) you be absolutely fine. Hope that helps - Jerry

[@alexhuevera939]

Are you sanding with the 40 grit after the Kitty Hair has completely cured?

[@mrsemifixit]

For a beginner looking to try a diy, how do you know which grit of sandpaper to use and when to switch to a higher/lower grit during the repair?

[@LakesideAutobody]

Here's a quick run down. I will do a video on that topic very soon. Filler work = 36 grit then 80 to finish it before primer. Paint work = 120 grit on the DA (rough sanding / feather edging) / 220-240 on the DA for paint work or finishing your primer / 120-150 for block sanding you primer surfacer. Rule of thumb is use what cuts the fastest but know that eventually you have to get it down to 220-240 (DA) or finer if you hand finish sand (320-400) for paint. Exactly like doing a wood project really. Let me know if you have any more ?s on that :)

[@mrsemifixit]

@@LakesideAutobody So the last grit before paint should be 400 if doing it by hand? Does that also apply after you’ve primed it?

[@LakesideAutobody]

@@mrsemifixit Last grit by hand is 400 - yes. If you use a DA the last grit is 220-240 or finer if you want. I finish sand my primer too just in case there are nibs or dust. You want everything completely smooth before paint. I keep a spray bomb can of cheap auto primer for any little bare metal spots left (you don't have to sand that). If any confusion ask again :)

Is it a trailer queen 4. was the job done properly where the filler was thick and rigid 5. Is there good drainage at the bottom of the panel This type of repair can last forever or less than 3 years so.... again it's how you take care of it after the repair.

What is a good primer in a spray can

[@LakesideAutobody]

Most primers in a spray can are very similar - they are good for priming bare metal before painting and that's about it. They are not high build or primer surfacers that can be block sanded. So.... I would just use the most inexpensive (rustolem, krylon, etc.) since you're just going to use it cover the bare metal before painting.

[@midnightraiin4035]

how long do you wait to hit it with the cheese grater, approximately ?

[@LakesideAutobody]

Depends on the temp inside the garage and how much hardener you added. The best I can say is when you can still dig your finger nail into it. Once you can't dig your finger nail into it, it's probably to late - but you can still try. Let me know if you are successful at it :)

Fiberglass reinforced filler is waterproof but hard to sand if you let it get too hard (cheese grate it before it hardens). If you can get to the back (often impossible), you can wire brush it and coat it with some undercoating. That will seal it for a long darn time - no water = no rust :)

His undercoater had a tip that sprayed flat to cover a wider area. The problem is that there are several different formats of spray tips and they are not necessarily inter-changable. Nice to use a WD-40 straw tip on an undedrcoater can IF IT FITS. -- I keep a variety of cleaned diff tips just for that possibility. -- AutoBody supply house may have undercoater with straw tips, or use a spatter gun -- small holes only if u have a straw sprayer

[@joelpalmer]

I respectfully disagree that 3/8 of filler is either necessary or desirable. That is close to half inch and is a ridiculous amount of filler. Filler is for a skim coat not to be troweled into half in deep divots and dents

[@LakesideAutobody]

That's not very respectful... The truth is, filler isn't just for a skim coat. The best body men I have ever worked with were not afraid of body filler and that is why they were great. You cannot be a good body man if you are scared to use bondo. It got a bad name because folks threw it over a hole and did not prepare the surface correctly. In 40 years I have never had bondo (no matter what the brand) crack, fall out, bubble, etc. If you fix and don't just replace panels you have to use filler. BTW, that's nowhere near 1/2" maybe 1/4 max depth after sanding. You want to see 1/2" or more you'll have to find the 1978 Lincoln Town Car 1/4 panel I repaired in the early '80s that side swiped a tree. Had to spread the filler on with a 12 inch piece of stiff cardboard :) Customer wanted to save $ on the repair but happy with the job.

[@joelpalmer]

@@LakesideAutobody Lets put it a different way. If you put a refrigerator magnet on it and it slides off, the filler is thicker than necessary. The underlying metal is too deformed for a professional repair. You can hammer out and smooth most metal in the time it takes to buy misx and apply a thick coating of filler and take most of it off with a cheese grater.

Yes it's a nice temporary repair, but to suggest "forever" or the same as welding, sorry physics makes that just factually inaccurate. That thickness of filler (in your video you said "at least 3/8" thick") will expand at a much different rate than the steel fender. After enough sun heat/cool cycles a microcrack will develop and moisture will get in. Furthermore, there is NO WAY there are no air bubbles in that thickness of filler. Again, expansion and solvent popping over time will eventually let moisture do it's damage. It's a nice mid term repair, but let's not pretend it's the same as a properly butt-welded in patch with just a skim of filler.

[@LakesideAutobody]

I've never had filler do what you say it will do in the sun, expanding metal, air bubbles and all - that's false information. Like I said in the video, If you seal the back and no moisture can get to the repair it can last forever - why wouldn't it. As for the but welding thing pls see this vid and also what Eastwood has to say about straight up butt welding - kzbin.info/www/bejne/m2rFm42Vit2ngMk Eastwood vid: kzbin.info/www/bejne/qKGrZmOhnZmKZpI Please see this video for longevity of filler repairs if done correctly - kzbin.info/www/bejne/bonEi3WvbKx2baM or kzbin.info/www/bejne/aKCWaJeOYpKqZqs

@@LakesideAutobody I'm not arguing the longevity of filler repairs IF DONE CORRECTLY. Your video said verbatim "at least 3/8" of filler. C'mon, let's be serious, any quality restoration shop would laugh at the statement that 3/8"+ of filler is correctly done. And since you asked "why wouldn't it?" Here's the reason thick filler is a problem. Because temperature change cycles acting on the different coefficient of expansion of filler relative to the steel substrate causes sheering forces at the bond interface which eventually leads to adhesion failure causing small cracks allowing the ingress of water and re-occurrence of rust. Not an issue with thin applications. But thick filler repairs ain't right. What's worse is how the filler squished through those existing rust holes to the backside, creating moisture points. Yes, short strand filler is waterproof, but the metal hole it's sticking through is not and again you have different expansion rates. Paint on the inside doesn't change that, it just delays the inevitable micro cracks and water ingress. There are reasons dent puller repairs from the old days (with filler sticking though the holes like worms on the inside) aren't considered permanent repairs. All that being said I do respect the fact that you posted a good method for a medium term repair that can be helpful for DIY folks that can't weld.

Please use a dust mask.

[@LakesideAutobody]

You know, I went to a lung specialist because of a spot in my lungs that was seen on an x-ray - I asked the doc if all this body work was the cause. He said, " there's no way any of that dust has made it to your lungs - too much mucus and stuff to protect the lungs" - I didn't believe it but he knows more than me about that stuff - I think he may be right - but I still wear a mask for sure.

Cheese grater is about 4 grit.😂

[@LakesideAutobody]

You're right - I like your thinking 😊

[@jong8024]

Feel as if it would've been a better option to take 5 minutes to plug in the welder and give it a few tack welds. Versus spending the time mixing glass, sanding the glass, then adding filler over that, sanding the filler and so on. And you're chances of that shit cracking and falling off in 4 months

[@LakesideAutobody]

This was for folks that don't want to weld or don't have a welder.

[@robertgreendyke8617]

Ah yes, the "only way is to weld" guy. Present on all videos that show us how to do a quick and dirty clean up on an old beater.

[@luismoreno4927]

Not true! my old Eurovan had a fiberglass patch for a year and it still works.

[@MindDezign]

That was good. But with 99$ at harbour freight for a flux welder. ? I mean any body can mig with 30minutes practice. And with Bondo getting to be " no longer a CHEAP fix. If you plan to hobby fix cars. Buy a $99. Dollar mig and a 25$ self darkening face helmet. Weld up sheet metal is not hard and you get better at it every 15 mins you use it. Other than that you always show good ways of body art. I hope beginners take note at the way you hold the tool and let "IT" do the work This is the difference between pro and amateur. Let the machine do the work. Stop pressing so hard, burning out Chinese motors!

Mixing this stuff right involves Black magic,...

[@LakesideAutobody]

The hardener is red so that would make it Red Magic :)

[@48Ballen]

you did a great job right up until you sprayed the "undercoating " on the inside. This product doesn't prevent and often encourages corrosion by locking in moisture and salt as it dries and cracks. A better approach would have been to clean the inside, spray it with a rust converter, paint it with a good rustoleum paint, then spray an oil onto the area that corroded.

[@littleredridinghood5622]

I'd like to see that repair with base / clear coat on it .. I guarantee you it wouldn't be pretty ..

[@LakesideAutobody]

It's perfect. kzbin.info/www/bejne/eX-5doGXqNymn9E This had the same repair done on it - even worse.

[@1keykneedeep]

Great video. But I would need $3000 in tools to repair a rust hole.

[@LakesideAutobody]

Not if you bought the basics at HF

[@michaelteresko7833]

Yikes !!

[@LakesideAutobody]

At the beginning of the video I stated "It's another method." I have many different videos showing many different methods. It's your choice what you want to do to your car. You can even lease a new car if you want it perfect but that's not what this channel is about. It's about helping each other out.

[@wrenchmanhotrods1247]

Sorry a real body man would weld a patch in that spot .

[@LakesideAutobody]

The title say's w/o welding. I have lots on welding - here's a playlist w/ a bunch of them - it's good to have a few so folks can do some body work if they don't have a welder - kzbin.info/aero/PLOP9eoG14-I-qu68_805bZaOnmkdlv6Ys

Yet another hillbilliefix

[@LakesideAutobody]

Not so - it can last forever if you seal the back from moisture.

[@paulyboy1951]

the music sucks. stop it.

[@LakesideAutobody]

Hey man! That's one of my better intros.
