there is no semi gloss or flat lacquer,you just skuff after its dry.
Not true. You can go to any automotive paint store and purchase a semi gloss clear coat. I have done that myself. If you "scuff it up" you will have lines from the steel wool. PPG does make a semi gloss clear coat. I have been painting for 28 years.
By the way Buglebuster, that looks pretty good. Did you do that from a rattle can or an airbrush? There is a technique to do that "rock finish" with an airbrush.
