Saw a thread on what appears to be bugs on non PPF, what is the best way to get them off the front bumper on PPF? I got about half of it done, still not perfect and it took quite a long time. i'm basically scraping them off with my fingernails. I know pretty gross. My fault for leaving them there for months. I've tried bug and tar stuff and it doesn't seem to do much. The echo waterless wash is doing nothing. I read people said to clay them and that seems to work the best, but I feel like I"m wasting a lot of clay.
