spray

So I got this FW1 stuff at a gas station (I know, I know, I shouldn't have done it. :mad:). But I may yet have some use for it. Whenever I get my car washed, there is some runoff that collects on the driver's side of the hood which leaves water spots. Could I use that stuff to get rid of that...

Has anyone had experience with these spray coatings? Seem almost too good to be true. If so, any recommendations? (....Sorry for the repeat post....don't know how to delete one.....)

Hi folks, i just bought ABRO undercoating spray, thinking to use it on wheel wells of my Genny, its written on it that its gonna decrease road noise. My question is that; can just an undercoating spray really do that job or its just a waste of time? Have any one tried that before any...
