Thank you all for sharing so much detail about your tire experience. I'm shopping for some my 09 Chalet and I've been going back and forth between Michelin or Goodyear. Thank you for the detail about Toyo having road noise but being better off-road. At this point I only see myself going off road a little bit when reaching certain campsites, so the lower road noise with the Michelins seem like it will be worthwhile for me. I look forward to hearing about your continued tire experience and will share mine as well!
As far as i can tell, it's an automotive protectant. Seems to be made for uv protection of car interiors. (I googled 303 spray and that's what came up)
Along that same line of thought, there are a number of rubber care sprays on the market. Maybe worth looking into?
It is a water-based UV protectant. It works extremely well on just about any surface. The selling point is that it is water-based and not silicone or oil. We use it on just about everything with excellent results.
