Got my '19 WRX and i'm trying to take good care of it. Want to put something on the door seals to keep them fresh for as long as possible. I use 303 on the dash/other inside plastics and love the results I get. I even use 303 on my game consoles/stereo equipment and it really keeps the dust off. Anyways, how do you guys think 303 would hold up on the door seals?
