Power Coated tonneau cover care

[Biga]

I love my Lomax tonneau cover but recently it looks to have faded a bit and their are large water spots that don't come off with normal washing. What is the best product to use on this? I was thinking maybe 303?

I used to use WD 40 rag to clean and “shine up” the black fender flares on Jeeps. It worked great and also helped keep mud and dirt from sticking during trail runs.

depending on your cover’s material and finish, you could also use a light duty rubbing compound on a DA sander. Just make sure it’s a LIGHT duty compound so you only clean and polish and not remove any finish material from your color.
