Just learning about these products. Glowing reviews all around. Excited to learn more and start using. I have a specific problem I'm looking to solve. I'll look around to see where I should post my query unless someone replies here to point me in a direction first. I have redwood seed tannin stains on my 2 month old 2019 rav4. I would like to remove them, reseal/coat the paint then get on a solid maintenance program that I hope will help manage this ongoing environmental situation. Unfortunately I have no options as far as covered parking. I'm hoping getting going on the OPT program will make it easier to mitigate this deep stain/etching problem. Thanks! -Chanda
