Let’s just put it this way instead of overthinking anything, the longer you can keep a freshly coated vehicle dry, the better it will be.
When I coat ANY vehicle, I keep it dry for a minimum of 12hrs. I basically allow 1 day for full cure. Then I top it off with its topper before sending it out into the wild.
You folks are just making something so simple, into something so difficult which is confusing most people that don’t understand coating application.
