GARAGEBULLS Hydrophobic Trim Restorer.

Stuff works extremely well. priced extremely cheap. And not tension it warns you NOT to get it wet the first 24 hours or t he first 80 washes. Which when I asked customer service...it's to help this stuff really soak and darken in the plastic trim. Awesome stuff, great quality, and excellent customer service.
And I've used a LOT of this trim restor stuff.
