Thread: Welding VW fenders to body questions

Tweet

Have you considered using a Bonding Adhesive like they use today in Auto Body Shops like Lord Fusor, 3M or Duramix? You wouldn't have distortion, and it is as strong (or stronger) than Welding, and is designed for Sheet Metal-in fact, Audi will now disallow structural Body Warranties if the Body is Welded-just a thought-

No not yet. I would have to modify the mating surfaces to make them flat against each other. This would not be a big deal considering the amount of work any route will take. If I flattened out the mating surfaces and bonded them into place, would I then fill in the crack where the fender meets the body with a glass type filler like Don mentioned above? If I did it right, the crack would be very close and hardly noticable. It seems that I would have to cover the crack with some kind of filler to keep the paint from cracking.

Yes, and after you bond them (and they kick), just use Rage (or your preferred Filler, but I love Rage). If you were still concerned about strength you could use some Kitty Hair or Tiger Hair, but I wouldn't-Rage (as long as your are within reasonable thickness limits) will flex with the Body and not crack-(Evercoat, (Rage's Maker) says 1/8", I think more like a 1/4")-

Thanks bro. My local auto body supply store carries Rage as well as kitty hair products. I'm going to stop by and get some more primer anyway so I'll ask them what they would suggest too.

One last thing-I like Lord Fusor (and use it), but you have to buy a special Gun to use the tubes-the Fusor Guns are about $30-40 (they are side-by-side, like a double barreled shotgun)-I believe 3M (?) offers it in a tube that you can put in a regular Caulking Gun-wish you were closer, I'd loan you mine-

And if you haven't used Kitty Hair before, put it on thin-that stuff is like concrete, you have to grind it and then put Rage over it-
