Thread: Patching Floor Pan on '72 Chevelle

Tweet

Welcome to CHR! We'll be looking forward to pictures of your progress on the Chevelle!

Just curious, why do you not want to weld in a patch? The "Right Stuff" approach is going to work fine, but a butt welded patch will eliminate the overlap joint which is going to be a moisture trap. Not saying it won't be good with the POR15 and Right Stuff, just wondering since a patch panel, or even sheet stock would not be that hard to do with the seat out.

Just curious Roger.So your saying a flanged patch panel welded top and bottom is a moisture trap??.

No, my comment was that IMO a butt welded joint is better than an overlap piece glued in place. I did not mention a flanged, welded joint, but IMO unless you do a full perimeter weld on the bottom side of a flanged (overlap joint) patch it will indeed tend to wick moisture over time.
