Hey guys, sorry to burst in but just to add a lil to the how to. Make sure you prep it very well. Use 1000 gritt and wet sand them, go get a gray scotch brite and scuff em up whatever. Also make sure you take your time, let the material get tacking or handslick, dont coat it on. When using rattle can clear always be caucious when you wet sand rattle can clear, there is no way of getting it to lay even, and you may burn thru.
