Yellowing headlight plastic

CRiZO

Do you drive through the desert? Those things are sandblasted lol.

I've used the Turtle Wax kit (the one for using a drill) on a decade old car, and it worked well it seemed. However a year later it seemed the sealant wasn't sufficient. A simple touch-up buffing and sealing took care of it though.

I don't know how easy our headlights are to remove, but I'd suggest going that route and using a power tool. May as well do it the best you can.
