Starting to paint! (Interior)

So I've started putting on primer. I'm using some old System Three epoxy primer that I had from 1994, so it takes a fair bit of mixing to get all the solids in suspension again. But otherwise it seems fine. I'm about to run out of it though so I bought some of their current product, which is gray in color so it will be different working with it.

No idea it would take so long working around all the stringers, bulkheads, and coves. But it is taking a lot of time. Trying to give 2 coats, as I'm not real confident in the thickness of my under coats of epoxy and I want to up my chances of waterproof-ness.

I'm definitely finding some of my areas of amateurish-ness in coving.. lots of little pinholes and areas of roughness.. but I have to keep forging ahead or this boat will never see the water again. I fix what is egregious and what is easy to fix.
