Zach, Sudbury Elastomeric
Sealant claims to stick to Starboard with no need of primer or other special prep. I haven't tried it on Starboard yet but Sudbury sent me some samples of Starboard glued together with the Sudbury
sealant. The samples are very impressive.
I used the sealant when I installed some
hardware. It was nice to work with and skinned over quickly.
From the Sudbury catalog.
"Adheres tenaciously without primers to
fiberglass, glass, plastic (including Starboard), metal and
wood. Simple clean up with mineral spirits. Not recommended for wooden
deck seams or use in areas subject to gasoline."
