Mother's Back to Black here also.

 

A big ol' fat +1 on this. 303 is from Jesus. I used it to keep the fenders on my Wrangler looking new, I use it to keep the plastic/vinyl/rubber on my Skeeter looking new, and I'm going to use it to keep the bed caps and my hard tonneau (Roll-n-Lock) looking new. My R-n-L even came with a bottle of 303 as a MFG recommended solution!

 

You should see what Aerospace 303 does for tires, too......

Like the previous poster - I got started on this stuff a long time ago - on a Sportmaster tonneau on a 93 S-10. It was the only treatment the manufacturer recommended. I, also, got a very small bottle with the cover.

The cover still looks amazing, and is in excellent shape. I treat it 2-3 times a year, dependent on exposure. (Yes I still have it - about to pass it on to my Grandson.)

Since then, I read the label, and use it on all vinyl, plastics and rubber.........'

It really is MAGIC.

 

I use that stuff everywhere. I have a 11 yr old tonneau cover which has been treated with this stuff on a regular basis and it still looks good. And I live where its cold and lots of snow. The stuff is great.

 

The plastic on the ram boxes fading or warping and the top of the bed caps fading or warping is a normal issue with these trucks, all covered under your 3/36 warranty

 

If the caps are just fading, then yea, even good old Armor All will turn them back black again and keep them black if treated regularly. I wouldn't use Armor All over the other products suggested, but it'd do in a pinch.

If they're warping though, then the dealer should replace them for you if still under warranty. I have a 2009 in South Texas that sits in the sun every day. I've had no issues at all with warping.

 

I finally took my Ram to the Dealer to have the Rambox caps check because of fading. They took pics and send them to Chrysler for approval and it got approved to be replace under warranty. Now Im waiting for them to arrived.

 

Mine look good, but I have a tonneau on them

I was not hot on the idea of these caps, always liked the bare painted metal look and leave it up the owner if they need protection.... But my concerns over the caps was not if they may fade, but what is under them.

When they do yours see if you can get a look at your truck with them off. How much dirt or scratches are under there?
