I recently had a Fenylab V2 system put entire car including rims and calipers. Car looks great but gets dusty sitting under car port. Was told not to use a cover for at least two weeks. When do you think it’s ok to just do a light spray off with just water?
General rule of thumb with coatings is not to get for 24 hrs as that is the bulk of the cure. Depending on product full 100% can can a couple weeks. However after a week it is ok to wash. If you are just watering off you are fine. If you have forced air I wold dry it that way to minimize any spotting ( yes coatings spot all the same).
As others have said, ask the installer. Usual pro grade ceramics will fully cure in 7 days, but can get wet (safely) after 24 hours - this all varies a little from brand to brand. Do not wash for a minimum of 7 days. I'm not familiar with the V2 kit, but know some of their self heal products need IR lamps to cure. That speeds up the cure time tremendously.
