I am currently preparing my 302 for a touch up coat of rattle can corporate blue paint. The engine has about 6,000 miles on it since I rebuilt the motor in 2004 and only minor oil/dirt was built up. I cleaned build up of oil and dirt from the engine using wax and grease remover and now need a general cleaner/degreaser recommendation to clean the engine with prior to scotchbrite and painting. What do you guys recommend? Gunk degreaser? Dawn? Formula 409? I am doing this in a 2 car garage and do not want to make too much of a mess... I plan to use a new sprayer I bought for weed killer with hot water for rinsing everything off.
