hey! my dad scrubs the front of revolver cylinders!...like i said we are both gun cleanness freaks...a speck of anything but shiny metal is not good...it will be taken off..i think i need something stronger..this stuff takes forever to scrub off and some still stays...i cant take having a dirty gun sit around...i dont care if its dirt on the outside and doesnt matter at all it will be cleaned if its humanly possible...any ideas of a stronger solvent or anything?
