Peanut butter and jelly is my favorite combination!
Since this is a CG give away tho: Some properly polished paint with 85Rd topped with CG Enzyme always looks great and one of my own personal but twisted combos!
I am currently using Wolfgang spray sealant and then top it with Souveran spray wax. Really works well on a light color car like I have. Both are easy to use with no streaking.
