Does this work on Starboard? Sudbury elastomeric sealant adheres to Starboard much better than silicone. It is the recommended adhesive for sealing/waterproofing behind starboard frames on tackle boxes and doors. With that said, it is not a substitute for mechanical fasteners and should not be used as the only means of structurally adhering starboard.

will this product fasten starboard to aluminum boat below waterline?
A shopper on May 7, 2018
BEST ANSWER: Hello, nothing really bonds well to Starboard so I would not recommend using any type of adhesive alone to attach a piece of Starboard to a mounting surface.
I am going to replace my Lenco edgemount trim tabs and will be using a sealant for the screws and for sealing between the trim tab hinge and the transom. Is this a good enough product for this job?
Ed Z on Apr 28, 2018
BEST ANSWER: Hello Ed, the elastomeric sealant on the is a very good adhesive sealant and is intended for use above and below the waterline so this should work great for your application. Please let us know if you have any other questions or if there is anything else we can do for you.
How well would Sudbury Elastomeric Marine Sealant work as a home bathroom caulk? I need to seal around the circumference of a sink that's slightly raised from its countertop (made of some kind of epoxy, I think), and I also need to seal a slight gap between the sink countertop and a vertical backsplash at the rear of the countertop. I also need to seal around the top of a tub where it meets the wall tile. The usual bathroom/kitchen/tub & tile caulks all have issues (some get yellow, moldy, don't smooth well especially if they're made mainly or only of silicone, etc.), so I figured maybe Sudbury's product might avoid these problems.
