That may be true, but a video found right here on this website of the guy applying it says that it should be ready to wipe off within just a few minutes. I never waited a few minutes, I was wiping off within 30 seconds most of the time. I'll also say that I applied it indoors, and then backed it up into the sun. I only did this b/c a gentleman that introduced me to adams said this is the process he uses for his corvette, porche, jaguar, ferrari, bmw, and truck. Hard for me, a rookie, to go against someone that's been doing this for years on far more exotic cars than I have. If it works for him, it's good enough for me. That was why I moved it into the sun after application. Yes, I did all the appropriate prep work before applying. The car looks great, except for those spots. Which are now removed. But now wondering if I washed everything off and need to re-coat.
