Opti Coat proved it's worth in spades spending this winter in Florida. I originally tried it to try to impart some hardness to the super-soft H-D Vivid Black paint. It worked! Not only is it more swirl-resistant but it prevents dealer hackedness...
Had my touring barge over to the Daytona dealer's version of Disneyland For Bikers for some diagnostics I couldn't figure out. They squared me around gratis and when they brought the bike out I saw they had washed it

It looked OK in the shade but I knew what I was going to be seeing in direct sunlight. Sure enough next morning every painted surface looked like they'd washed it with Brillo.
I brought a limited amount of products south with me along with my GG6. A light polish with by hand with Hyper Polish confirmed all the damage was in the Opti Coat rather than the finish.
After 20+ years of parking in a heated garage I figured parking the truck outside in Florida was no problem, right? I was amazed at the amount of pollen on the finish...visible even on white...combined with the residue from salt air and heavy morning dew made it look like someone barfed on the horizontal surfaces when it dried. I resolved to get out in the morning and wipe it down while the condensation was still heavy. A light spritz with ONR at QD dilution aided in preventing the majority of marring. What little that was accumulated over 3 months is easily removed with the lightest dose of Hyper Polish. I'll give the finish a thorough polish and refresh the Opti Coat when I return to Ohio.
An aside...after spending 56 winters in the Great White North I've seen the light. "Snowbird" has a nice ring to it, I expect to be basking in the sunshine in the winter every year from now on. I think I'm getting the hang of this retirement thing. Im the MAN
