What do you use to keep exterior plastic from fading?

My plastics (bed lining, side view mirrors) are still black and I want to keep them that way. What products have you found to work best?

FYI: I've heard some people use WD40 but a little research found that its not sustainable since WD is slightly acidic.

 

I use mothers back to black or Adams VRT.

 

aerospace 303

a true uv protectant that nautical/avionics use

 

I use Ultima Tire & Trim Guard on all my exterior rubber & plastic trim. I apply it about every 3 months.

For my tonneau cover I use Aerospace 303 Protectant.

Be careful applying any protectants in the bed of your truck. Could make it extra slick.

 

This. 100%.

 

Thanks guys but how long after applications do you notice fading and have to re apply?

 

should reapply every month or so, although I only do it every other month as aerospace 303 is a little expensive. I have not noticed any fading, and my trim still looks brand new.
