I am finishing a minor rust repair at home all the other steps are done. It is now in the final coats of clear coat from spray cans from AutoZone and wet sanding with 2500 and 5000 grit. It’s a DIY job. How long after it dries does it need to cure before I can use Jescar Power Lock Plus paint sealant on the newly painted areas? I could not find a recommendation anywhere. Also, should I use a light buffing compound first, or go straight to Power Lock? All the regular prep directions make no sense since it’s new, clean paint.
