Hey guys im trying to plasti dip my grill but I want to tape everything off before I start. Im having some trouble getting behind my grille so I can tape it off or drop a piece of cardboard behind it before I start painting. Here is a picture of what im having trouble with. I take out the 3 screws in red but the piece seems like its still attached where I have drawn the blue. Any help or advice would be greatly appreciated. Thanks!
