I'm thinking of touching up the lower unit paint on my 08 Yamaha. I've read several articles on line about what and what not to do but thought i would throw this out there and see if anyone has done this before.
If you're just doing touch up, you should be able to get the paint from a Yamaha dealer, preferably in a spray can. Touching it up should be pretty straight forward.
But if you're looking to have a paint shop spray it for you, it might require some extra steps and prep.
Either way, light sanding would be recommended to help the new paint adhere better.
