I have a 2000 Blacktop convertable and the top is starting to fade. Are there any products out there that can restore it? Also it makes a wierd sound when its not warmed up, kinda like a straining sound when I turn the wheel.. but the power steering fluid is filled! One last thing.. I also need a tune up.. what kinda of replacement plugs and wires should I get? any other suggestions?! thanks!
