LOL,labor intensive heard.My job consists of dry sanding,wet sanding,and buffing of RV's at Lazydays.If you don't know,some of these RV's paint jobs are in th upper 70-80thousand dollar range
so being a perfectionist is worth it.
Off the shelf products,I like Mother's or Mcguire's.I would also recomend aplying it with an orbital polisher and work it in really good.This cuts down on swirls and lays a good protective coat on the clear.Also,don't go using a regular towel to take wax off,most good paint supply stores sell 3M products and micro fiber towels,I get all I want free
I wish I could help about the clear questions but I too am still learning that process.
