I have mowed with my B2650 and mmm for 3yrs, and has been great. I have tried alot of things over the years to protect the bottom of a mower deck and have never found a miracle coating. The deck came painted, and the bottom has held up pretty good for 3yrs. I do keep it clean throughout the mowing season also to keep it in good shape. I decided to just repaint the bottom seeing how it lasted good for 3 mowing seasons. I took my 4 1/2'" grinder with wire brush and prepped it. I am going to prime it and then paint both with a brush. My question is for those that know more about paint then I do, to recommend a paint that would work good for this application. The ones I am thinking about are regular Kubota paint, my farm store has a Valspar farm and implement paint, or I painted something a while back with Rustoleum and was surprised how thick the paint was, but dont know how well it would hold up for this application. I would appreciate any thoughts on the subject. Thanks.
