Yeah, they're talking about fiberglass bodies. Fiberglass bodies and parts are fine, especially on race cars. Lots of cars use composite bodies of one kind or another. That's not what I said, not even close.
Slathering a steel fender in fiberglass resin is a whole different ball game. Especially if you're fixing a HOLE. So let's recap, since you're not following. Driving a car with composite bodyparts- just fine. Using fiberglass to repair fiberglass or composite parts- also fine! Using fiberglass to cover up rusty holes in a
steel bodied car because you're too lazy to do it right- POS move.
Yeah, none of that is using fiberglass and resin to cover a hole in a steel fender. Body filler, used properly with good prep, is fine. But it's not meant to be covering
air is it now? It's also not mean to be very thick, but yet incompetent morons will slap it on a 1/4"+ thick and be long gone when it cracks and falls off. Just because a product exists does not mean that every use of it is legitimate.
Yeah, I saw your thread with the rusty holes, galvanized screen, and bondo over the top to hide the damage. Just verifies 100% you're not qualified to use Play-doh, let alone pass off anything you're doing as "bodywork".
People who use screen and bondo to cover rusty holes belong in the lowest level of hell. You're not fixing anything, you're
HIDING it. Those quarter lips on your car would rust out SLOWER if you did nothing at all. Your screen and bondo trick will not seal, the bondo WILL absorb moisture, and it will now be trapped in the space behind the bondo to breed more rust. Maybe it takes a few years, but the bondo will swell up, the rust will continue the entire time, and eventually the whole thing will fall apart.
How do I know? This is my Challenger not too long after I bought it. For the record, I knew it had a bunch of bondo because the guy I bought from had bought it online just based on pictures, then realized after he had it in person that he'd been royally screwed over by flipper lowlifes and was in over his head, and turned around and sold the car at a
substantial loss. I knew it was rough, but it was also a running, driving E-body that I could afford so I bought it anyway.

This is about 3 years later- the bondo is swelling up and the rust is bubbling

4 years after that. Yeah, some inbred, mouth breathing degenerate bondo'd over a rusty hole. There's a piece of sheet metal sandwiched in there between layers of bondo to cover the hole. It held up long enough to rip some dude off on an internet sale, and the "repair" was so absolutely dog **** that full quarters are the only way to fix it now.

So yeah, don't sit there and argue that screen over a rusty hole with bondo on top is a legit repair. It's 100% unadulterated bullshit perpetrated by scam artists and lazy POS's.
