A lite spray of oil , WD or the like . btw , it's worth mentioning that while you can "pack" a .22 or pistol can with grease , you do NOT want to do this with a rifle can . THe preassures can do interesting thing's to the suppressor
Just squirt it into the first baffle. I find the pulling gel makes a bigger mess and is not as effective as just dunking your suppressor in a cup of water.
I bought a big 'ole bottle of clear wire pulling gel. It sucks. Even tried mixing it 50/50 with water. Still sucks. Plain old tap water goes into my HEMSII .45 cal. 10ccs of water. I would use less in a .22 can.
