I got the spray bottle ($1.00) used it just the way it came. Cleans great. Didn't rinse, but didn't let it sit too long and just wiped it dry. Then I sued a spray app of "ICE PREMIUM CARE" Maxx Protectant by Turtle Wax for the UV protection . Great finish and I will see if it holds up any where near as the 303 I've been reading about so much on this forum. I'm not knocking the 303, it is just easier for me to get this stuff locally.
And OOOOHHH that protectant smells soooo good.
