Clean and Re Grease – one of the best sayings we have ever heard is “a clean car is a happy car”! When you have a clean car it is much easier to see any problems before they become an issue, whether it is a crack in a bulkhead or a screw ready to fall out when your R/C is clean maintenance is a Ultra easy! We recommend a couple different products to clean your R/C including Cow R/C chassis wash and Cow R/C silicone spray to keep everything clean and shiny! The silicone spray for water / winter driving is always a great idea as it will repel water to help keep any metal component rust free after application. Bearings, internals in the differentials and axles you can use a good waterproof grease (Cow RC Udder Butter or a marine grease), to put a light coating on to ensure they also stay rust free.
