red loctite on my empire on/off = MY WORST ENEMY
it started to leak so me and the gun techs tried to unscrew the leaking screw thing & it stripped completely w/ one turn

i had to replace my on/off on that marker
the refs said that just hot water or a blow-dryer would work (as people have already said)
it shouldnt mess up the anno on the markers w/ better paint ( i can't vouch for spyders tho)
