I used a two part product called Epo Strong for filler on my frame and transmission housing before powder coating. Regular filler isn't conductive so it can't be used. I have thought about using it for filler in places like the firewall.
Thats a good point that its not conductive for a powdercote procedure.

Good point well made sir! I agree too, JB Weld is a strong bonding and sealing product. I have used it for pin holes and small pitted ares that after properly cleaning the spots lasted forever.

Helicopter use~everywhere....

i was considering using it as a small area (less than 1 inch) instead of leading because it is near a window in an older mercedes.....I used to fly helicopters for a living and I can tell you for a fact JB Weld held all our gearboxes together....and every other place they needed it...so as far as heat and vibrations....it doesn't get anymore demanding than in flight....what say you?

I did exactly this. Had a few tiny pinholes... tapped them in... metal prepped... sanded... filled with JB weld for the strength and water-tight seal.... then sanded and covered with filler.

I only did it because of the holes, and don't expect to again.

So far no problems.

I would not consider using jb weld as a body filler, although something very similar is often done on urethane bumper repairs, using a adhesive that has some flexability for the majority of the repair, and regular filler for final finishing work.

If I was stuck on using epoxy as a filler, well then I'd probably use an epoxy fairing compound, like I've used in the when working for some boat builders (basically bodyfiller in marine terms). Its a 2 part filler as a base and convertor must be mixed together.
Haven't really seen any bodyshops using it at all. although I am sure somewhere some place might, but fairly commonly used in the marine industry.http://shop.sailnet.com/product_info.php/products_id/38 I like fiberglass filler when a bit more fill or a bit more water tight filler is wanted then comfortable using plastic filler, but would actually prefer using the epoxy filler over all metal junk that I was forced to use a whole lot of at a past job.
