Chameleon Paint Still Falling Off

I’ve put different chameleon paints on 2 different vehicles, several times now, each time they’ll usually stick initially, but a day or 2 later after parking it will fall off. It has happened to me multiple times on the coquette and just happened to me again on my bison. Also the neons under both vehicles, again, seem to turn black the same time the paints fall off. Very very annoying. The paint job isnt cheap and neither are redoing the neons each time they turn black. PLEASE FIX THIS!
