In this episode, I tackle cleaning up the engine bay for paint, removing decades of old paint and grime, and fill a bunch of holes on the firewall from the original heating, A/C and electrical connectors.
I'd like to smooth the firewall on my 74 Duster. The B body has that seam or pinch weld running in a nice symmetrical arc but, the A body one isn't so nice looking. Can that just be cut smooth and then, can you run a bead along it to attach the two sections again?
Yeah, if I didn't have the nice looking pinch seam I would have just welded the two panels together, ground it down, and used body filler to smooth it out. That approach is probably more structurally sound regardless.
For making round patches, tack a pin in a piece of sheet metal. Fix it to a drill and rotate the piece while grinding off the corners with a grinder. Eventually the piece will turn round and then it's just to grind it down to right size.
