Unlike most tractors I work on this tractors castings have never been repainted so there is no paint to remove, just a thin layer of rust. I do not like sandblasting and am able to remove most of the rust except in small areas with different types of wire brushes on angle grinders. What is the best way to remove the small areas of rust and then what is the best thing to use to kill the rust in the castings to keep if from coming back? I have tried several products at the local hardware store, but have had problems with the primer sticking.
Thank you in advance
