works perfect absolutely amazing product takes a bit to get the hang all 4 pieces age differently so it looks pretty bad i tried spray coating and all the the black tape does an excellent job of masking minor imperfections in black trim of turned all the chrome around my windows black love it works great if you have the patience to poor quality control a year later and it is still there 2 years later its still holding up and looks like new i love this stuff great to cover up trim that is looks great and has held up to washes and rain for easily scarred when i tried applying to vehicle window trim blackout your chrome without paint
