So I did the Klasse Kit today and the results are great. It was getting dark while I was finishing and im not sure if I buffed it all out. If I didnt get every part would it be ok to spritz water on it and then buff it out? Or since I will have driven it by when I do it I should wash it again and then do it. Also will it come off easy if it sits there over a period of time even in the sun?
