how do i get a yellow bug stain off

Great! you know where I can find a white bug big enough to cover a 3 inch stain

I'm still trying to find the name of the moth that hit my car last spring! You might actually get some good info on cleaners and such , from a local detailer in your area the guys/gals that do that on a daily basis would have the best experience with your specific situation.They have a detailing department where I work , but all their cleaners and stain removers are no-name packaging , so I couldn't help you. Hopefully my original answer gave you a laugh ,instead of pissing you off, usually people post a question and never reply one way or the other ..........but really I just couldn't resist! Good luck with your stain.
