A perfect paint finish may require many hours of block sanding to get a metal surface that’s straight and without waves. Heed our words when we repeat that a slow, careful effort when performing these steps will be well rewarded in the end. After all, you don’t want an exterior finish that has imperfections. Despite the fenders being brand new we still checked the smoothness of the metal surface. After the metal is misted with paint, it’s time to use the long sanding blocks. Use slow, long, back-and-forth movements to ensure the long block is moving straight over the metal surfaces. If any black paint remains on the metal once you think you are done, you have a low spot. If you sand off the guide coat and the original primer coat and reach bare metal, you have a high spot. Either way, take your time and do it right. View Related Article
