The right type of lubricant
Im looking for an all-airsoftpurpose lubricant or grease, for making anyhitng slick. I want one that can be bought at canadian tire or walmart (dont want to order online). i be using it for a lot of different things and i don't care about the price. another question. how rough would sandpaper have to be to remove spray paint on an airsoft gun without leaving any traces or scratches.
any advice for either of these questions would be helpful.
