RE: anyone in Vancouver B.C. Canada
living out in the "beach" you would want to use after run oil at the end of each running day, i know what it's like out there. i lived in north van for 10 years and the salt in the air out there is murder on anything made of metal. like ehroof said it's cheap insurance. that guy will never steer you wrong. wd-40 is good for cleaning the outside of your rc but keep it out of the engine. if you ask anyone on this forum about ehroof they will all tell you he will never give out bad advice, he really knows his stuff. plus he is really good guy, he never made me feel stupid for asking a dumb question( ok it was a noob question lol). actualy nobody on this forum has made me feel stupid for asking any question at all. i have heard of some guys using "marvel mystery oil instead of after run oil but aro is only a few bucks, and well worth it i think.
