I have an old beater of a car, a 1986 volvo wagon, i don't think it has been professionally cleaned ever. I am looking to clean it up big time, since i have a lot of free time on my hands. I plan on washing all the interior cab by hand, shampooing the rug, and put seat covers and floor mats in. I also was thinking of armor-alling the dash and panels. I saw it for 6 bucks a quart in wal-mart. Does that stuff work, is it a good deal?
