I don't have any laying around at the moment so I can't give you a name or a brand right now, I got it through and used the double barrel gun from a "body guy" friend of mine. I'll try to get the brand and the source info from him. It might even be something from NAPA as I know he uses alot of materials from them, the stuff costs about $50 for double tube setup of about 16 oz. total volume or so as I recall.
