Well, after 2 years of driving a restored car, radar let me down and I got caught in the rain for 15 minutes, when the radar even said it was not raining where I was. My dilemma is Sand!! The water picked up sand under the body, especially behind the rear valance leaf spring area. Any idea on the best way to remove? Wait until it dries then hit with an air gun? Try now when it is wet? I have the car in a ac garage with 2 fans blowing under it to dry it out... I hate the weather channel app!!! I am a true believer in driving your car but this Rain killed me. I heard flooding the underside is not a good idea to get water in the seams.....thanks for your continued support.
