RE: Carbon Blast
If you are spraying it on camo, staining isn't a big problem. You can see it on certain camo patterns. I don't think it works any better than the other sprays. Plus the other sprays allow you to sray all your clothes with no staining. For 2 bucks I'd probably pick some up for my boots or outer suit and just deal with the mess and hassles of it clogging up.
