Thanks to all who have posted replies to my questions. I'm still working on the curbside and have yet to find anything that will remove the "brush marked film" that was under my clearcoat on the street side so I'm assuming its part of the aluminum. I've tested a couple of areas and it seems that the film comes off with several passes of G6 or F9. (and I thought streetside would be easier.lol)
Again, thank to those who have responded and I'm sure I'll need questions answered on other projects as time goes on.
