yeah i sanded the chrome down a bit with 120 or 240 i forget. Just enough to scuff up the chrome nicely and then i painted it with krylon plastic paint in satin black. I love the shine on it cause its not gloss and its not flat and sorta contrasts with the tank when its not pledge up.
Textured would be cool, ive seen people use spray on bedliner, thats a unique look. Probably pretty hard to remove if you dont like it though.
