I want to paint the underside of the deck in the cuddy area, the underside of the sliding hatch and rear "cooler" hatch cover.
I know they will not be smooth, I am fine with that, just looking for a nice clean look.
I repainted the underside of the deck in my XK22 with regular old Petits Unipoxy White paint. It has had up well for years. I prepped the underside by spraying it with a bleach solution to kill some mildew and the soap and plenty of water. The only thing I might have done differently would be to add an anti-mildew compound to the paint since I have had to take care of a little mildew over the years. But I just brushed it with a good brush even though it wasn't fun or clean with having to lay on my back to paint the area.
I'd check with Petits to see if they recommend adding something like that and maybe you might want to use it in the cooler area if you plan to use it for food or fish.
