I have an aftermarket rear hatch decal. It is a little smaller than the stock decal but should be sufficient. I was aligning it on my hatch tonight preparing to apply it when I noticed my original decal is still on the car. All the lettering is faded but the old decal is still there. Unfortunately my decal is not an exact duplicate so it won’t cover directly. I think I can probably live with it though. My question is whether the new decal will even stick if installed over the old one. The old one is not peeling and is in good shape except that all the coloring is gone and so I can see the paint underneath. It’s a California and Texas car so the plastic rear bumper and spoiler are pretty faded. I guess the rear of the car got a lot of sun over the years. Any info or experience is appreciated.
