I have considered using black Plasti-dip on mine. I used it on the straps of my windshield last season, and used something similar from Rustoleum, called Flexi-dip, on the wheels of my Wrangler. I like the idea of being able to remove it if I change my mind. The stuff also protects and inhibits rust. Just a thought. - But if you want a cheap spray can that's permanent, I recommend the Rustoleum spray cans. Coverage is wider and smoother than Krylon, IMO.
Keep moving, learning, loving, and living.
