This topic comes up alot. I've used alot of so called remedies but what I found that has worked for me the best is some stuff called RV-455 I got it from a fellow racer Dave Ribeiro his e-mail address is
[email protected] or you can call him at 757/810-1832. Tell him you got his name from me, Vince Tosto.
His stuff works great. I'm sure other guys have some great stuff too but this product worked for me. Beleive me I used alot of different stuff.
