I used JBweld to fill in chain rash on frame I'm hopping it will OK to powder coat over... Has anyone used JBweld fill
Prior to powder coat?

I recall some discussion on this. If you use the original JB weld not the quick set, it's good for 500F which is just below the bake temperature. From what member Txpowdercoater has said, he uses JB weld. There can be issues with pin holes from out gassing, but he deals with it.

He did a frame for Bikerscum in a beautiful purple and spent quite a bit of time filling and sanding and smoothing with JB before PC.

I remembered that too Dave. I think I found the post you were referring to.

They make a high heat epoxy. That's what i used on my frame before txpowdercoater did my frame last summer. I want to say it's good up to 1200°f
