John,
when you do a butt joint you have to gring down the welds on the inside and do bodywork to hide it.Read the final part on Partial quarters.
you can grind the inside and smooth it with filler then spray with Paintable Rubberized Undercoating
then just paint as usual.Mopar but heavy
undercoat on the inside of the trunk area on
most cars.
Once you replace any quarter it's not original
butt welded,plug welded,tack welded,or bonded.
any good bodyman can tell if a panel has been
replaced no matter how good of a repair you do.
It may be consealed under the moldings and such
but the proof is there.


AZblackhemi,
I edited the procedure and added the welding of the rear seam.Was trying to stay away from that cause not everyone has a welder and the stuff
required to bond panels is less expensive than a welder.but I put it in cause you all were pointing it out.I know that,i was tought it.
I was trying to eliminate them needing to get a welder for a few welds.

thanks -Jeff
