My brother taught me that trick years ago when he restored a 68 Camaro RS/SS. He had Cragar SSTs on it, no junky rims and was doing body and paint. Also taught me this one, when wetsanding a car, lay newspaper on the ground to catch the sanded primer etc. The newspaper will catch the sanding chips, water will filter thru, and your driveway or shop floor wont end up with a mess you will have a hard time removing. I had no idea the N.Y. Times was actually good for something lol.
