if you have vinyl graphics on your car do you just wax it like normal or do you have to avoid the vinyl? if so can you use quick spray? what about buffing? will this tear it off or scuff it?

do not wax your decals i did on mine and they started to crack

And you get a buildup of wax around the edges of the decal. It looks like crap unless its a white decal on a white car

I have a red "H" emblem on my gascap door, I wax it whenever I wax the rest of my car, I have no fading or cracking. It still looks the same as the day I put it on. Its true, wax will build up around the edges, but you can easily get it off with a toothbrush or any other soft bristle brush. I just use an old toothbrush I had sitting around.
