Best filler for pot metal?

[woody80z28]

I cut up my fender vents to use as trim rings with my newly welded sheet metal vents.

What can I use as a filler on the back side of the pot metal? I'm worried about adhesion. I'm thinking along the lines of "Lab-Metal" or another metal reinforced filler.

I know it sounds redneck, but you might want to consider JB Weld. It seems to give good adhesion, and you should be able to file it into shape after it sets up.

that 3m 2 part body epoxy with the special applicator gun pretty much works on everything.

Use them as a mold and make some new/ better ones out of fiberglass?

What 3SLO5 said. 3M 08115
That's what I used to bond my vents to my fenders. Holds great and you can file and sand it after it hardens.

I've never liked JB Weld...it always shrinks on me.

Panel bond sounds like a good idea, I've already got the gun for it.
