If you use silicon I don't think any paint will ever stick to it. I've
used sikaflex for seam sealing on aluminum aircraft floats and it
works very well. It'll be messy but lay a thin bead along the joint
then force it in with a plastic squeege and scrape off the excess.
You'd be able to paint the next day. I found 2 places in London Ont
that sell it.

You know where we can find this flexible epoxy paint? i live in
Ontario.

Does the epoxy paint seal the seams where two planks overlap as well?
or do i have to caulk with silicone stuff as well?
please reply, im itchin to get on the water.
thanks

Use a flexible epoxy paint and not the clear brittle epoxies used for
laminating and repairing etc. That will seal and waterproof but still allow
all kinds of movement of the wood as the uncoated sections expand,
contract, swell, etc. Such epoxies are generally pigmented so you could
paint and be back in the water in 24 hours or so. Come fall paint over the
'epoxy primer' with whatever you like.

I'm just finishing up the restoration of a rotting 1/4 inch plywood dinghy
in this manner - Even with epoxy inside and out, the plywood still has the
flex it originally did (in the non rotted or repaired spots - cleaning the
boat with a modest water blaster literally shot a 5 inch by 5 inch hole in
the bottom and a few smaller holes too!)
