I use to work for Masco Tech/MSX International back in 96&97. We painted the hoods for the Dodge Viper GTS coupes. The blue ones with the white stripes. All that we used on them after they were wet sanded was 3M polishing compound(I forgot which one), followed by Meguires #7 Yellow wax. The results are outstanding.
One of my winter projects if I don't get to do a lot of snowmobiling, is going to be wet sanding and wheeling out my car. No more factory Orange Peel Oxford White on my GT come spring time.
