im going to paint my deck with awlgrip. its currently sprayed gelcoat with non-skid. dont try and convince me to stay with gelcoat, i already have the awlgrip. i know i have to use wax and grease remover before i start sanding the deck. my question is will there still be tons of wax getting in the way of my sanding, ruining the sandpaper and such??? or will the product get rid of it totally with the 2 rag technique ???????????
