my 79 (new) repro quarter is covered in mud. quarter skins are junk , once you get it on they are so wavy. but the hole car has it. but with dings and dents pulled, its not a 1/8" thick . really I'd say its no more then a 1/16" thick.
guys that brag , or want a no filler car. dont know what they are talking about.
the f-body is one of the most waviest car out there.
I talked to a guy at the NATS too. he worked in the decal area. he said by 77 they had a body shop to take them to for rework.
