This is the absolutely the best stuff I've used over the past 5-6 years - Chemical Guys Blazin' Banana Carnauba Spray Wax.
Not only does it provide very smooth surface protection, UV protection, and applies as easy as any product ever used...the best value is to get a 1/2 gallon and fill multiple spray bottles for handy use.
Bought a 1/2 gallon @29.99 - it filled (4) 16 oz spray bottles @ $7.50 each.
OH YEAH - and you can use it on painted surfaces, trim, glass, virtually any exterior surface.
