colej If you’ve done paint in the past the prep work is what makes it breaks a really good to great paint job. Do you have all new panels?
I say leave it original
No new panels. All original, door gaps are really nice but could stand a touch up here and there. No problem doing that on fiberglass. There are 2 factory seams where the panels come together about 18" from the taillights on both back fenders that have a vertical line top to bottom. Barely noticeable. Gravy to fix that, just a skim of filler. Other than that very straight, but I will get it as straight as possible. I'm very fussy, so I will spend the time it takes to get to my goal.
