Resin compatability with paint

Hi,

I've recently acquired an old waveski (sit-on surf kayak) which needs some repairs. Once this has been done, I want to give it a fresh look to cover up the old faded colouring and decals but not sure the best way to approach it.

At the moment I'm am thinking of the following two options to keep the extra weight to a minimum:

1. Sand the existing fibreglass slightly, paint with a water-based acrylic (most likely Liquitex spray paint), and cover with a coat of laminating resin.
2. Sand the existing fibreglass slightly and cover with a coat of pigmented laminating resin (most likely solid white or black).

My question is, will I have any compatibility issues or delamination with option 1, and will option 2 give me a solid enough colour to cover up the existing markings?

A third option would be to pigment a fresh layer of fibreglass to the ski, but this will add 1 to1.5kg of extra weight which I wanted to try and avoid.

Any help would be great!

Wood is a solid Material, 1k laquer isn't. The epoxy might glue to the very surface, but in the end, everything ontop of the 1k laquer just floats on the painted object.
1k rattle can laquer is really not a good idea for basically anything that needs mechanical surface protection.
