Just picked up my CR-V recently and saw there were some rust spots on the towbar and underneath where it attaches.. I guess it was because he lived near the sea as i can see it around the front and rear brake disc but no where else. With regards to the rust.. as its only superficial.. I was planning to use my anglegrinder and a metal brush attachment to clean off the rus, and then paint it with hammerite smooth black. Would you recommend this method or another? I don't know the make of the towbar but i guess it must be from Honda? p.s thinking of doing this to the edge of the brake discs / calipers as there is a small amount of rust layer. Thanks heres an image of the rust.. anyone know the make?
