We used some Fusion to paint some receptacles in a custom home once. After a few hours it seemed like it was tough as nails--it didn't scratch off with my fingernail very easily. BUT, a few days later it scratched off quite easily.
You're probably just as well sanding first with 180-220 grit (nothing finer) to give it some "tooth". THEN go for some sort of bonding primer--go to a paint store that serves contractors (such as Sherwin-Williams, PPG, ICI/Glidden, etc.) and tell them what you are trying to do. They should be able to steer you in the right direction. It could help if you know the exact "plastic" of which your kayak is made. There are many, many different types of plastic.

I'm not sure about Marine parts like a Kayak but,
When I worked for my dad, We used plastic prep from 3M after we sanded the plastic parts for cars. Like I said, I'm not sure how that would go with full on all water contact, but I'm sure its similar. We then coated it with Variprime, and then Uroprimer, sand that down slightly, then paint.

Go to a Marine (no, not the USMC) store or visit www.westmarine.com and look up info on boat paint, or even colored gelcoat. Try the product advice link.
A decent topsides paint will be durable and a bit flexible, and when combined with the stuff they recommend for getting the paint to smooth out (and applied with a quality fine brush) you can't tell it from spray-on unless you get yur eyeball right on it.

A guy down the street from me is (was) a painter. His house was an almond vinyl siding. He cleaned the siding, then sprayed some sort of 'primer' on it, then painted it white.
That was 15 years ago, and he has moved since then.
The house still looks great! It has not been repainted, either.
With that said, you might want to check with a paint store, i.e. Duron, Sherwin-Williams, McCormack, etc. (Not a place like Lowe's or Home Depot.)
Just a thought. . .

Sounds like a roto mold poly yak which has alot of flex and oil base. Try a test spot inside but first wipe down with lacquer. There was a additive for paint before spraying on plyable airdams which prevented cracking. Check with a good marine supply. I have a Necky Arluk 3 in kevlar but then that's a hard shell, S.F. bays my playground.

Sounds like a 'what'????? You lost me on that word "roto." The rest of it has me moving my index finger up and down on my lips, mumbling, "Buh . . . buh. . .buh. . .buh. . .buh. . .bub."

Where they pore liquid plastic in a mold and rotate the mold until it cures to prevent a thick puddle on the bottom, even thickness thru out the hull.
I see your not a kayaker or been following their progress the past 20 years.

(J/K.)Sounds pretty 'slick' the way you describe it.
Thanks.
