Hi All, I installed a sprinkler system and what I was afraid of came true, my car has developed a nasty yellowish runny stain that I dont know how to remove. I am pretty sure it came from the sprinklers but not 100% positive. I can take pictures if need be but I was wondering if anyone had any suggestions for removal. I have tried Washing, and using distilled vinegar to no result.. I was thinking about using goo-gone but wanted advice from the experts first. Any help is appreciated! Thanks Rich
You might have to clay and polish. Pics would be helpful. Etching on paint can be very difficult to remove and sometimes permanent.
