Re: Will vinyl decals stick to King Starboard?
I ran my first boat for 4 years prior to painting it with the numbers affixed to a starboard panel hanging in the side of the cuddy cabin. They stuck just fine to it. I'm sure they would peel off if I tried but they never washed off or came unstuck on their own. Just make sure you clean it well before applying your decals.
The adhesive warnings are most likely meant for structural joints, in which case you would need to either use a mechanical fastener or heat to properly join the stuff.
Think of it this way, they make sign panels from similar plastics and apply vinyl to them. Also, many of the lighted signs you see are made from Lexan or Plexiglass which are lettered with vinyl lettering.
If your using a textured version, I'd apply some heat when applying the decal then make sure the surface is super clean. No textured surface is ideal for vinyl application but it can be done with some success.
