Is it ok to use Wolfgang finishing glaze before using the Blackfire coating prep? I occasionally get brand new trucks in my shop, with the dealer installed swirl marks. They are very light swirls, and come out very easily with light polish. I am trying to limit myself on how many different products I have to keep in stock. (Trying to save a few bucks if that's even possible) I realize the glaze has oils in it to "wet" the paint. Does the coating prep remove these oils, or do I need to keep a seperate finishing polish in stock for light swirls. I like the WG glaze, because it seems to break down faster than heavier polishes, so it saves me a lot of time on the big trucks I get in here all the time.
