Long time, no type. I have missed this community. Long story, but, life has kept me out of the garage and off the forums.
The short version: How do I remove Ziebart Diamond Coat?
The Back Story: I just bought a new 2018 GMC Sierra 1500 Denali in black. Love the dealership. Have bought many cars there over the years, but, since my last purchase, they take all the cars on the lot to Ziebart and have them apply the Premium package and try to sell you the service. I understand. I never buy those. No big deal. Until now.
It looked good when I picked it up. Cloudy day. Then it rained later that day. So, I pulled it in the garage for a waterless wash. After cleaning it, I noticed MULTIPLE water spot that I couldn't get out. The idiots applied the coating over the poorly prepped surface. Including water spots and a few areas of dirt. I need to remove the coating and the water spots. I would much rather do the work myself than having them or the dealer.
So, to the question: How? I assume polish? I own multiple polishers and polishes. PC 7424, GG 6inch, GG BOSS 15, Flex 3401. Also own multiple pads and polishes from Megs DA MF system to M105/205 to BOSS. I understand least aggressive, test spot....
I guess what I want here is, how hard is the coating and how aggressively does it have to be removed as your experience has taught you? Just trying to prepare myself for the task at hand.
Thanks guys. Glad to be back on here.
