help with vht nightshade tinting lights
 

hey guys im tinting my headlights today with this vht nightshade spray tint and want to know exactly what to do, i have scuffed the lights down real good and cleaned real good with windex and put my first coat of paint on them now waiting to dry but i think i may have went to heavy of a coat b/c they are alreadly looking dark enough for me but also they are showing alot of imperfections in the headlights themselfs, like some areas look smooth and clean where some areas look like they are dull and protruding out a little bit help please????
