Priming over lacquer

[vettnut]

1960 Corvette. There are patches of the old factory lacquer primer (low spots) in the engine compartment, interior and trunk area. Some are a bitch to remove. I do not have or know of anyone with a soda blaster, that is a another subject. Tired of the hand sanding at this point. How big of a deal is it to leave the patches of this 50 year old lacqer primer under my future primer surfacer? I plan on scuffing all with 80 grit to give teeth to the primer surfacer. NO, these old corvettes did not have gel coat. I use PPG products and Evercoat Featherfill for my primer surfacer. Have Dupont and Sikkens in town, but prefer to stick with PPG. I will be eventually topcoating with bc/cc in the engine compartment trunk and interior, and of course the exterior, all with the same paint. This is a restomod car. Thanks DG

As long as the paint is gone and you only have some of the original primer on interior surfaces you should be good to go with primer and paint.
