I guess that I am a 'hack'. I have rolled it on with a small (3 inch roller from Lowes) with much success.
Thin it as recommended, roll it on, and lightly sand. I use rustoleum brand and paint a truck for under $100. Worst case is you get an '8 foot paint job'. If in the future I want a 'professional' paint job I believe I can strip this off and do it that way. I currently do not have the money.
I also use my trucks (55 2nd and 53) for work and not as trailer queens. I don't put them in competitions and have no trophies. I am fine with that.
Go for it. My 2 cents.
