that might be because you laid it on to heavy if you use plastic paint or automotive paint and do 2-3 light coats you should be fine mines holding up great lasred all winder and still looks the same and i just used black plastic paint from autozone lol didn't feel like bringing it into the shop and tape it all out and mix the paint to do them so i did it at my house. and no i didn't take it off just jacked it up and put it on jack stands to make it a little easier. and did you sand your last one before you sprayed the color? if not that's why. if you do this wet sand it with 600 grit
