I bought a small can for like 35.00 and coated my interior of my cab and it turned out awesome!. Soooooo a buddy of mine was like "well I have 3/4 of a gallon that you can just have!. Sooooo I have gotten really bored in the last few days and have gone crazy with the stuff. My frame, whole underside of my cab, inner fender wells, and even my front suspension has been painted with the stuff and it looks awesome. When I say suspension I mean the TTB axle housing, not my coils or shocks or anything. I also painted my radius arms. My truck is already black so it all looks good. My front end axle housing was faded and had some spots of surface rust, now its all painted new like. Anyone else gone crazy with this stuff?. I get bored and can't leave well enough alone!
