I had my front nose re-painted recently and it is bubbling up badly. If I leave something like a bug or bird poop for several hours on it, it leaves a mark. I will take it back to the shop to get it repainted but I'm wondering if there's any way to avoid this from happening again? I'm guessing that the material used on the front nose(urethane?) isn't so easy to paint but factory paint on the nose seemed to hold up much better. Any ideas?
