Exactly... I don't want to risk the possibility of abrasive wax... and D301 might be okay, but now I am more worried about any wax being too hydrophobic for the interior. I remember applying Klasse AIO on my interior glass once a long time back, and at first it was okay, but then there came a rainy day that I battled the foggy glass syndrome. That's why I think the recommendation for McKee's 37 Plex-All and/or Brillianize might actually be the better choice. Both of those offer polymers with protection, slick finish, anti-static and anti-fog properties... at least from all I researched, which is a pretty good bit.
And I need to make a correction... it was not the manufacturer (Prestige) that recommended a silicone based polish, it was the dealer. The way it looked in the dressed up email from the dealer that mentioned silicone polish made me think it was something the manufacturer was recommending, since the dealer had given me a card with Brillianize written on it. I have not clarified with the dealer yet why the two different recommendations, but I did call Prestige, and they said they don't really have any recommendations outside of using Stoner's Invisible Glass Cleaner or Meguiar's D120 (which I have and is less cost) or something similar. Manufacturer did say the Spectra Photosync was extremely scratch resistant and very durable. Nick at Prestige had never heard of Brillianize or applying silicone polish or wax. So I am curious how the dealer comes to this conclusion. Granted he has been installing tint for 30+ years, but still curious why he recommends what he does. I have sent him an email.
