hrrcflyer, Sigment is a product from Sig Mfg. You should be able to get it at the hobby shop if you have one near. It comes in a squeeze tube. Kind of like the clear plastic glue from Testers that we used to use building plastic model cars in the day. AAHHH I can smell it now................ an origional glue sniffer. I remember building rocket engines in my teens which have evolved in todays world as pipe bombs. Lucky I didn't blow my fool head off, well I'm rambling on about what it was........regards Sugarfox
