A while back I was interested in getting into airsoft and saw couple video on custom hi capa but I never really full dive into until recently and learn all the component to building one. Plus it like closest thing to owning an actual gun. My real question I been seeing people using Waldo lube and there is like three version thick, thin and medium, how do I know what to use or is there one that just works with anything. And lastly I do see people say to use loctite on certain screw areas so they don’t fall off, how do I know what screw I can loctite? Is there a guide because I saw some video where they show couple areas while other show only one. Any tips help thanks
