As they say in the UK..(Been watching too many Cash In the Attic...lol)
One of the best ways to determine whats in the make up of any product, is to grab the MSDS sheet for that product. In this, talking an Airstream product, the company has taken the guess work out of the process years ago~! You really don't need to be reinventing the wheel here~!
lol, just spend your money for the right product and, keep your A/S happy~!
BTW, this stuff is not that expensive~I've seen it priced range from 13$ to 16$ dollars a pop.
