Anyone have any tips on installing a graphics kit. I have a tank and shroud sticker that I am gonna attempt to put on my bike. Should I scuff the plastic? I really don't want to do that but I heard that it makes it stick better. I have also heard that if you spray the plastic with Windex then apply the sticker you can move it around a little to get is set right where you want it. After the Windex dries the sticker wont move. Anyone ever try this?
