"Base layer"? WTF? There is only one layer in the hull of a 2010 Jackson kayak.
I don't think there's really much you can do with a crosslinked boat, because you can't weld crosslink. With a linear boat, you could do some pre-emptive welding, which might eliminate stress concentration at sharp corners in the scratches, but even then, I wouldn't do it unless it's a really deep gouge, because the weld itself can compromise the integrity of the surrounding plastic.
I'd just keep paddling it, and if it does crack through, then bitchothane the inside and fill with epoxy on the outside. Or get a new boat.
