Filling pitts in bumper, preping for Powder coating
I am curious what to fill the old rusty pitting with on my '67 bumpers. They are a little rusty. I am going to have them blasted to clean them up, then I need to fill the pitting to prep for powder. I was considering filling with my mig, but that seems too labor intensive. Will the lead substitute stand up to powder coating? Or will it melt out? I can post pics if needed. I am hoping that there is a filler that I can use to smooth it all out.

What ever you use needs to withstand the media blasting!

I'm worried about the heat. I figured that I would have them media blasted before I make my repairs, not after. I was worried about the heat of the powder coating ovens. I think the guy told me the ovens get to 300? i may be wrong. Metal body filler may work, I wonder how much heat it would take? I'd hate for it to melt out when the bumpers are in the oven!!!

FYI. Powder paint ovens temps are typically 320F-400F.

It may be easier to find a non-pitted core if yours is that bad.
I don't think they can powder coat non-metallic items so plastic body fillers etc are out. Lead melts at about 327 degrees so that wouldn't work either. You'll also need to get the chrome chemically stripped before you bast it. |

I think you will have to weld them up. Either that or paint them instead of powder coat.

Close on the Eastwood stuff, but this is what is used. Used it on pitted wheels and then powdercoated them.

I would try a metal type filler that mixes like bondo. I think its called All Metal.

There is a high temperature version of Lab Metal that stands the heat of power coating.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
