Just my 2c-

I have a set of sanding pads that start at 600 and run to I think *3500* grit. I will be reiterating a bit some of the advice from above.

Simple fact is- if you want a mirror polish you need to start at about 600 (maybe lower depending on how coarse your biggest defects are) and go through an SERIES of steps up to 2500 grit or so. THEN you can use a rubbing compound (very fine) or a polish to finish it off.

As has been said before, Novus is completely useless on clear coat as anything other than a cleaner.

I do not find that I need to spend the really big dollars on a 3M kit, get a set of sanding pads to 3500 grit (or something like this) and step up from 600 - 3500 using as many as 6 different pads between the two, you will finish with a near mirror. Then a very fine rubbing compound or polish will finish it.

Using a quart of clear is a little heavy for a PF but its likely not an issue... but do give it time to cure. Depending on which clear it may only be a few days to cure or possibly a month... read the product information and believe it.
