Actually, I did get training using some of the items typically incorporated in a blowout kit. That's what made me consider buying combat gauze in the first place. (I didn't know how expensive it was, otherwise I wouldn't have turned down the free offer of a kit in the course. The instructor had given me some other freebies, and I didn't want to seem greedy.) Sure, the training I got was very basic, and I'm looking to get more training in the future. But I'm not adding things I'm entirely unfamiliar with. Thanks for the advice!
