WHat is the BEST filler for a good and long lived BODY REPAIR with rust?? BONDO is JUNK!!!?

Well, Robert, if you KNOW how To use Bondo, it is a GOOD proDUCT and it SEVves it's purpose.

yOU ARe supposed to grind hte rust off BEfore using any boDY FILLEr.

Bondo green with fibers, bondo pink, no fibers or j b weld, are the only epoxy fillers I know. Take a grinder with a stone wheel and really grind the area to clean metal. Go back a few inches to make sure there's no more rust dots. If the holes are small enough, just use the filler you chose, if real big then bondo a piece of 25 gauge stud metal to the inside and fill the outside smooth, prime and paint. I've done this to the top of a car 8 years ago and it's still a good repair.

Best Body Filler

hi there

holts is a good body filler i have used this many times it comes in a tin or you can get in a small tube this is better for small area and the best way to repair is rub it down so that it is rust free apply a small amount of filler build it up abit so that you can rub it down to make it level and primer and paint

hope that this helps

I'd say no to being a vampire

First you need to remove loose, flaking rust with a wire brush. Then apply a chemical, I purchased at an auto supply store but can't remember the name, which will bond the remaining rust to the metal. It turns black. After drying for a couple days you can use your bondo or other body repair material.

most any "5 minute epoxy" will work fine for your small project. It is cheap and sandable / paintable and is structurally stronger than bondo type fillers

it doesn't crack or chip and just build it up higher than needed and then sand it down even to the surrounding area

just sand out all of the rust and keep the grit below 320 (rougher) so it will give the glue/epoxy something to grab onto.

Gee just gonna use some body filler to cover that rust up Robert? there's a good idea. lets half @$$ this job, in that case might as well use some Play Dough, and whats up with your caps lock? if your typing skills are as bad as your bodywork skills I'd seriously consider professional help in this matter, personally I'd use products such as Por15 to contain the rust as best as possible and then the filler is just preference,

At that temperature, assuming that you mixed it properly, this is going to take a touch longer. commonly, you are able to sand interior quarter-hour or so after it has initialy set. on your case, i'd wait 0.5-hour to an hour to be secure. initiate by gently sanding with a very high-quality grit to confirm if the fabric is dusting as against getting gooey. you are able to help p.c. it up slightly by putting a touch warmth interior the room close to the restore. do not practice the nice and comfortable temperature on to the restore. in case you get it too warm too straight away, the restore will likely not bond in any respect.

Robert,I've been a body man for many years.From what you describe,a small $20 sandblaster should do the trick followed by bondo.Bondo brand really isn't that bad when used properly.And when used over freshly blasted steel it will last a long time.
