Our local auto parts store has this product too. There aren't many videos of it on youtube. I think I found 2-3 is all.
I'm wondering if it's similar to LiquidGlass? Both products, it seems, are in a class of their own...meaning they're not your typical abrasive compound or polish let alone your typical paint sealant.
In fact, I believe both LiquidGlass and TR-3 to be resins of some sort.
LiquidGlass, at least the bottle I looked at the other day, can be used on BaseCoat/ClearCoat paint systems, while my research of TR-3 has been a little complicated.
Reviews of TR-3 on their website sound as if some in the past have used this product on BC/CC paint, but I've noticed their "about" page eludes to it being used on BC/CC though there is not an official recommendation.
Actually, the last time I looked they seemed to change their less than "official" recommendation from eluding to TR-3 being used on BC/CC to now NOT recommending it...as those red labels now indicate.
In the past I did not see the red labels on those cans and their website "eluded" to the product being used on BC/CC. Again, that has obviously changed.
Here's a thought:
Most paint systems today are BC/CC. So, who are they really marketing to?
