I just finished rolling on the paint on my 71 monte. polished it and it has dull looking spots. I believe that the spots are from where i did not wet sand well enough with the 1000 grit. Can i go back over these spots with wet sanding and then re-polish or could it be something else. I used liquid ice by turtle wax for the polish as I did not do a great job painting. First time ever painting a car. I used semi-gloss black paint made by rustoleum. I cut the paint 50 50 with mineral spirits.
