I have an old roll of aluminum foilParts have turned a matte white which doesn't come off Safe to use?
NoRifling any barrel requires specialized equipment that only smiths and gunmakers haveAnd there no going to bother with an airsoft.
why, thats really pointless
It means the aluminum has oxidizedJust wash the white stuff off and dry the aluminum foil with a clean towel and it should be good to use.
