here we go again,
piss on buying stain magic, make your own, the best is one part ammonia and one part 30 volume peroxide from sally's. however to me thats still too much pain in the ass, so I just mix ammonia, a little water and some cobbs powder brightner together each time I need some, its fresh and works just fine and can't got bad. everyone should have powdered peroxide on their truck anyways, only thing that sucks is the soda ash that is the carrier for the powdered peroxide does not dissolve very well, it can clog sprayers up, its best if you mix it hot and let it sit a bit to help dissolve that soda ash
