Just had my 9' Pro Am (Black PRC) delivered 3 days ago. Mine doesn't have any of the other issues you mentioned, but I did notice that the PRC rails smudged up really easily. So I grabbed a pack of 75% IPA wipes I had lying nearby, and damn near had a panic attack thinking I'd ruined the finish! I've never seen IPA harm a set finish like that, but it smeared and looked hazy and terrible. I was able to keep rubbing at it to see that it didn't appear to be permanent damage, but came here looking for cleaning tips. Thanks for the Chemical Guys Total Interior suggestion, I just ordered a bottle to try.
Also have the Diamond ball polisher coming; my local dealer did the install and had driven to the Diamond factory to pick up my table the day before, but forgot the polisher! So I have to wait for his next trip. I have the Aramith cleaner/polisher combo kit already. I also have a bottle of Brillianize cleaner/polish that was recommended here that I used to use for hand cleaning balls. Has anyone tried it in the Diamond polisher?
