Trial and error !
Number of Items: 1
Just used and had to apply a second coat And still some sun bleached spots still bless through ! I don’t recommend ! P.S. my vehicle is only five years old ! So it’s not like it’s been sun bleached for ten or fifteen years But having said that , For the rubber gaskets around the windows and inside track on the bottom that is black as well And gets dirty all the time , this product works great !
