While detailing a customer's vehicle today I learned something that I had never tried before. The customer had sap on his hood and trunk and he asked me would I be able to remove it. Of course I told him yes. He asked had I ever used Rain-X to remove sap from the paint (and of course I hadn't). He suggested I try it to see how it works and offered to retrieve some from his garage. I told him that wouldn't be necessary because I had some readily available. To make a long story short - I put some Rain-X on one section of a MF towel, dabbed the sap with it for a couple of seconds or so - and to my surprise the sap came off as if I it was jam. Simply amazing I thought. Caution - it mitht remove a little wax, but I hadn't waxed the car yet so that was no problem. Even so, in my opinion it didn't remove any previous wax at all. I guess you never get too old to learn something new that really works. I just wanted to share this info with you guys.
