I thought my white hoods were six feet under too. I cleaned them up with Clorox spray and they were brilliantly white again but a few days later the tackiness was back. I sprayed Plasti-Dip on an old crummy set to test the process out and it worked, but only just ok. Then, by accident, I was cleaning up a frame and oversprayed spray wax - Mother's Carnuba (sp?) if that makes a difference - and the overspray hit the hoods. I wiped it off the hoods and... Voila! Nine days later and they are still white and still not tacky. Your results may vary, but what do you have to lose?
