Wow guys... thanks alot for all the feedback! I really appreciate it
So my initial concerns have all been resolved. Looks like the humidity won't be a big deal and I should clean with water first then put rubbing alcohol before the PD. And I think I will buy a can or two of the glossifier and try that out as well.
There were a couple of you who had some VERY valid points which I didn't think about. (Item 9 and Blze001)
Applying coats vs masking efforts: I will be doing all 4 of my wheels on my truck. I will be paying careful attention to my masking which means I will be spending a lot of time on it. Since I forgot about the PD ripping off when I unmask.. what should I do? If I'm expected to apply 7-8 coats of this stuff, unmask, remask, then reapply each time its going to be a PITA. I was originaly going to mask, paint, unmask and be done... but if I do that it sounds like I will just peel the PD right off afterwards.
