Hi. I need to repaint the bottom of my Honda powered Toro Proline mower and repaint the bottom of my HRC216 Honda mower. I dont really care about the color as I am just painting under the mower deck. What kind of paint should I use? I need something as smooth(durable would be nice too) as possible, we get super bad rain here and everything clogs like every 20 feet of mowing no matter what. I also have a lot of dings and marks in the bottom of my Toro due to rocks and other stuff that gets run over, should I fill these in with some sort of bondo or JB weld and paint over them? Thanks!
