Re: Epoxy + Oil-based primer
It is a moot point now since you have already applied the paint.
But if you had asked beforehand, I would have questioned the need
to paint at all in an area that is well coated with epoxy, is not
seen, and is not exposed to sunlight. I would not like to have an
area of a wood boat that was sealed with no access.

One (nonpaint) note on enclosing the buoyancy space on your Teal -- I
e-mailed Jim Michalak a few months ago after one of his web articles
on buoyancy, asking the question on my mind at the time -- if you
seal off a space like that completely, do you run the risk of it
bursting somehow on a hot day, or contracting and cracking in the
winter.
Well, he didn't really address that peculiar quesion, but he did very
explicitly warn against permanently enclosing space. Said even if
it's epoxy-coated in there, you run high risk of getting rot. (Anyone
out there with a years-old enclosed buoyancy space to testify about
this?) Jim recommended making a small, sealable hatch atop your
buoyancy space so you can air it out occasionally. I put one in my
Toto, about 10" square, and it's easier than I thought, and useful,
too. I'm going to go back and put one into my Windsprint now.
I can post the instructions for making one, if you like.
FWIW . . .
All best,

Hi all,
My Teal is to the part where I am painting- at least part.
My tampering with the design is to enclose the space from the
temporary frames out to provide some boyancy when swamped. I am
painting the inside of that space before I put the lid on. I have
epoxy-coated the stuff in there too.
Here is what is interesting. The paint does not seem to want to dry.
I am using an exterior oil-based primer. Still tacky on the
epoxy-coated areas after 24 hours. Dry as a bone on the stir-stick.
I am very glad that I won't be able to see this one the boat is
finished. ( it is inside a floatation chamber.)
So, I figure my options are:
Wait it out.
Heat it and wait it out.
Find a different primer for the areas where you will be able to see.
(Any recommendations on primers that cover System3?)
Seal it up tacky and forget about it.
Any others?
