I was putting sun screen on my arms before golfing. Some of it missed and got on my truck door. It did some damage to the factory paint job. It will take serious buffing to get the stain out.
I made the mistake once (once!) of putting sunscreen on my forehead before golfing. It mixed with sweat and leaked into both eyes. All I can say is, don’t ever let that happen to you. Much agony ensued.
