Hi Ken and welcome to the forum, the font of all knowledge (in Blighty, at least).
When you have a moment it would be nice to post a few pictures of your build, see the FAQ bit on the home page.
There is not much that is right or wrong about hull finishing. In most cases just a coat of undercoat/topcoat paint is more than sufficient, but everyone has their own methods.
Good luck with sorting out the advice! It is worth bearing in mind that most boats only spend a few hours in the water over a one year period…
