Bed Rail Caps Replacement Options???

Hey guys hope y'all are doing well during the Coronus Pandemics

Got a question for y'all and need some help, didn't figure it out till now (few years too late) but my bed rail caps on my crew max arnt fully messed up but they do make you itch like crazy. Looked into it and I guess since it's the originals and 10 years old, weathered from the sun, some fiberglass has started to break through I think. The itch has happened to multiple people but never thought anything of it till recent.

So should I replace them and if so does anyone have any good options they can steer me towards

OR

Should I just have them Line-X

 

Hey, Did you ever come up with some alternatives? I, too, would like a better rail and gate cap than the OEM plastic.
