Never knew there was smooth, mien is the Rough Textured Kind, I was gunan do my front bumper, but this stuff, i cant get the Car Wash mit near it or it will pull all of the stuff off of it, and leave it on there, So i didnt I jsut got some spray paint and went at it... Now my stock frotn bumper, i bought that cheap spray paitn can bed lienr from advance auto, it isnt as rough in textured, its jut like sand got mixed into the paint, it didnt grab the Wash Mit as bad....
