Aero Shell 33MS meets mil-spec requirements. About 10oz is just over $20 with shipping. Most people who buy it won't ever need to use the entire thing, so less than 10% of a tube for a couple bucks seems reasonable. I'm not sure what you're comment was implying, unless you're suggesting someone may offer it free...smarty pants. If that's the case I obviously wouldn't oppose. I just wanted to put my offer out there, because it would save me almost $20 and some people won't give anything for free...just ask my girlfriend. j/k
