Quarter panel skin advice

[Ryan77]

Hey friends! Will soon be welding in quarter skins on my 68 coronet. I'm debating on the long cut that's made across the top of the panel. Would it be better to leave a half inch then flange with spot welds? Or make a straight cut and butt weld? Would like to get some opinions. Thanks!

I did mine on my 68 Bee with a butt weld. It's a lot of off and on fitment but I did it to show a seamless repair on the inside. The lap weld like your mentioning is fine to just be sure to give a good coat and seal to keep moisture out of the lapped area.

That's my concern about the lap. The weld through primer is supposed to help but I'm not too sure about it. I believe more what your saying about sealing it off.

If you were to do a lap would you just do spot welds every two inches or weld the whole seam?

If you but weld it take your time & weld a 1/2 inch at a time. Also weld an 1/2 inch at one end then go to the other end. This will help it from warping. Ive spot welded a 2 inch piece on the car & then butted the quarter to the car, spot welding that on then fully welding the seam. This will give it more structure & help it from warping

locate the skin where it fits best with screws, overlapping at the top..... cut both at the same time and butt weld, one tack at a time spread out, cool each one with an air blower. also, I would work as high as possible just under the bend, using it for a little rigidity

Do as eldubb440 says^^^^^^

I don't lay any beads, all tacks to form a solid weld. Heat is your enemy!!!

Thanks for all the replies! Very helpful

a 1/2" weld on sheet metal is too much heat PERIOD.

I would weld the whole seam. Have plenty of clamps and somebody to help. Take plenty of measurements, and keep fitting till it's right. It takes a while to weld up the seam but do it in random tacks like everyone has said to keep heat down. I had a little warping but nothing a hammer and dolly don't fix.

Agreed

there are some good sites to show you if you hadn't ever replaced one and then there are some really bad ones

Ive done many quarter installs. Full & halves I never had a problem with 1/2 welds. Just do them further apart
