Painting
Dave;There are several things you need to know first about your Hunter 26. If you sand and it is still under warranty, you will void the warranty.Secondly, when pulling the boat up onto the trailer, you will scrape off the paint on the bunk boards. Third, you need to have the boat lifted in order to get to the centerboard and trunk housing from beneath the boat. Finally, most anti fouling paints will loose their effectness if left on the trailer.Several suggestions. First, you can rough up the bottom of the hull with a Scotch Brite abbrasive pad but would recommend calling Hunter for the correct one to use in order not to void the warranty. If you do not scoth brite the hull, a non sanding primer would be suggested for example Pettit 699 but if you use this nonsanding paint/primer, roll the first coat of anti fouling paint on while the primer is tacky. Secondly, you will need to lift the boat off the trailer to paint the centerboard and housing. Forsafety precautions, I do not recommend painting the boat while sitting on the trailer. Third, you need to look at the paint you will use to see if it will maitain it's anti fouling properties while the boat sits on the trailer. I like the Micron CSC paints which I put on the boats all the time for your purpose. Over the years, I find painting in the evenings and not under the hot sun, you will get a smoother paint job and do suggest using a 1/16 nap roller.
