SGF vs Cobalt
Recently I won an Sgf and a Cobalt gun from Ebay.
Both were completely clogged and covered with paint, so I got them cheap. I took them completely apart, used paint remover to clean all of the paint off, and then reassembled them using the original Teflon seals. Now they look good-as-new.
There's not much to rebuilding them.
Like everyone says, the problem isn't in the gun, unless the vent is clogged.
Most likely it isn't that either. I assume the Sharpe guy tested the gun after rebuilding it.
BTW Does any one know what the difference is between the SGF and the Cobalt?
They look like the same gun, just different color.
