Prepping Old Paint

[DennyG]

:dunce: I have a series of what may seem like odd questions to those with OTHER types of experience.
I`ve done 30 odd total restorations/streetrods/racecars,but have NO experience at "normal" bodywork.
EVERY car I`ve done was blown completley apart blasted to bare metal and built from there.
I now have a 68` Plymouth that is for my wife and I and has most of its original paint and it is in great shape.
Soooooo,how do you prep a partially assembled car?
I.E. how do you get GOOD paint adhesion on all those tight nooks and crannies?
what do you put over the old paint before new topcoats?
is degrease,scuff,epoxy-and paint enough?
CANNOT stand to see paint peel.
Told ya it was an "odd" question.........:goof:

As long as the original paint is not cracked or peeling you can just clean it, scuff it and paint it. No primer is required.

Adhesion should not be a problem if the surface can be scuffed. After cleaning I'd probably use 400 to 600 grit wet sandpaper on a sanding pad for most of the work or you could use the same grits on a jitterbug or DA sander on the bigger panels. On jambs and tight spots you can get away with a gray 3M Scotch Bright pad to dull the surface before you clean and spray. Where you think there could be an adhesion problems in a tight spot you can clean and spray with an adhesion promoter.

Len, does your clean, scuff, and paint opinion hold true for OE lacquers and enamels? Any risk of solvents in the base coats lifting the OEM paint the way they can lift uncatalyzed base?
