Hey guys. In Rockford, Ray Beard was tellin me about a product that can hold up to high heat not like bondo. I have a frame with a small ding that I would like to fill before getting it powder-coated. I know bondo wont work but what about JB weld? Hey Ray, what is the name of that stuff? Thanks, Jason AKA - The 26incher

I was told by Prism powder to use a product by the name of Lab Metal. I found an online source and ordered a tub. The stuff is similar to bondo but its aluminum reinforced. I had some difficulty using the product on small dents. I found is worked better on larger dents.

I have not used the product since Rockford and have not powdered the frame yet, it was spray can painted for Rockford. My experience may not be typical. Past performance does not indicate future performance.

Anybody else have any experience with this product or similar products?

Hey guys- I don't know if either of you saw the Ashtabula I had at Rockford, but when I got it the dropouts where wasted and there were a couple of good sized dings in the downtube. I filled them in with brazing rod and filed them back down using a DA with progresively smoother paper. On the dropouts I did the final shaping with a smooth hand file.
I've got a PK that I'm working on now, and I'm doing the same thing with aluminum rod. As long as you work slow and do small areas at a time you won't overheat and warp the frame.
Good luck to both of ya.

I have an .049 thick Chromoly Rigid that had dents in the chain stays, I used silver solder, and filled them then finished off with a file, and progressive sanding. You cant even see em.

On some of the quality steel frames you could use a small, smooth hammer at the outside edges of the dent.Lightly hammer around the edge. The steel has spring abilities and you could get most dents out or at least part of them. Then silver solder is the way to go.
