After reading my ad I should have specified the factory bumpy paint is the lower body has a gritty aka bumpy paint from the factory. I guess GM thought this would be chip resistant. GN's that have been repainted will no longer have this bumpy paint. The factory "orange peel" paint could be called "bumpy" too

Alot of these cars are prone to get cracks, fisheyes and spider webs over the years.
This paint looks like the day it left the factory...bumpy paint and orange peel. LOL! No cracks, fisheyes or spider webs. Its a wonder these cars are not real bad quality since the plant was closing down after the final Grand National rolled off the line. Quality in 1987 for any GM, Ford or Chrysler car was average to say the least. I am surprised at the 7 GN's I have had, no squeaks or rattles.
Now the 1989 Turbo Trans Am Pace Car I had, that is another story....
