Well I'll give you that for s kin or something, but as far as cutting something like a cab corner or upper wheel arch and using it alone, NO WAY. I left the rivets in the bedside the 2nd time around and it STILL cracked back loose. The cab corners are holding up better, but last I checked one has a crack line in it. I can find the stuff I used still have a tube of it, bought it from raybuck who I bought my parts from and they said it was used to bond metal together, I cut out the old rusty stuff, left it 1/2 inch longer then needed, flanged it, laid my new replacement over it, it fit flush. used the glue in the joints, held it in place with some screws for over 24 hours, said at least 12 or so, and full cure time was 12 hours I think or 24, dry time was like an hour or less to the touch. I removed the screws, ground edges a little bit, applied fiberglass/duraglass over it, sanded smooth, bondo'd to feather it in, sanded smooth, prime, paint. The bed sides didn't last, soon as I got the sanding close their were hairline cracks where they met, ground it all off, pulled the panels, cleaned off the glue, reapplied, screwed it down, drilled holes, put in rivets, let cure for over 24 hours, took out screws and replaced with rivets, ground the heads down, then repeated the before with the glass and filler.
Door skins I'd bet it work just fine, the quality of it holding the 2 together is good, it just didn't keep the gap tight and let me filler crack, and no it wasn't thick, probaly not even 1/8 total on both the glass and filler combined, it was really close right off, just had the slight gap to fill where they met.
