Plastiderp is good if your runner doesnt see much offroad, there have been waaaaaaayyyy too many times I've seen it used and a tree branch or even washing off some serious mud pull it off too or cause it to peel. It doesnt come off easy after that happens too.
When I did my Tacoma, I used rattle can bedliner or paint for it. Liked the rattle can bedliner so much i did the rocker panels
Here was before
After i decided to suck the color from it
On my new runner I would rather vinyl wrap the chrome rather than use plastiderp
never been a huge fan after seeing what happens to it after a few trips on the trail.
