Opti-coat products are designed to bond with the clear coat, and while they are safe to apply on trim and other materials, it doesn't bond and will come off easily. Over a 4-year span of maintaining several vehicles that have been opti-coated, Garry has seen discoloring on black trim while paint continues to retain gloss. Wheels are many times clear-coated so it will bond to wheels in most cases. There's also a difference between opti-coat, opti-coat 2.0 and opti-guard. Opti-coat was the first product (obviously), opti-coat 2.0 was improved to allow customer application, and opti-guard is a stronger coating that professional detailers can get their hands on. So if you see any opti-coat documentation that tells you it's safe to apply on windows, trim and other items, it's just marketing lingo. There's a difference between safe and effective.

Hmmm....I'll call David at Optimum to confirm that regarding the trim. As for Opti Coat being the first product, you're wrong. Opti Guard was the first product and it was only available to pro's. Then came Opti Coat which was more user friendly for consumers. And Opti Coat is safe on glass. They put that disclaimer on the bottles in case any DIYs mess it up and leave high spots as it could cause the view through the glass to become distorted. It won't last as long on the windshield because of the abrasion from your wipers.
