Upon returning from a week-long trip west, where it was 100+ degrees, I set about cleaning the assorted baked on bugs from the front of my brand new CX-5. They came off the new paint quite easily and seemingly from the gloss black plastic top piece of the grille as well. But when I looked at the part closely in reflective light, I noticed that squashed bug residue was still visible in splotches along the surface. I have tried everything imaginable to remove the splotches, with the exception of abrasive agents such as plastic polish or baking soda. It appears to me that the bug debris has literally etched into the surface of the material, which is hard to believe because this happened one week. I know this can happen to clear coat if bugs are left on too long, but plastic?...in a week? The next logical step would be a plastic polish, which would probably work if the part is a solid piece of acrylic, much like a motorcycle windscreen. However, if it has a coating on it, and I fear that it does, it may be essentially un-repairable. One thing I have not yet tried is Mothers Back-to-Black, which may help the appearance, although it probably would only mask the splotches, rather than remove them. I can probably live with it as is, but since it is brand new, I would prefer to get it back to factory perfect as possible. Does anyone else have any experience with or opinion on this issue?
