What causes the tar to set up? If, like paint, it's evaporation of
solvents, then it may never set entirely. Most likely, the solvents
will seem into the wood. What effect? Since it's meant to be used
with wood, I suppose it would be a preservative, like the old turps /
pine tar / creosote formulations.

If low cost epoxy is the goal... these two places are the best I know.
They sell for $27 to $30 gal (U.S.) and that is for a gallon or two, NOT in quantity.
Prices vary some with viscosity and hardener speed.

I can't buy epoxy for the same price as roofing tar by volume. But I
can't spread out roofing tar anywhere near as thin as epoxy, So
cheat that I am, I am figuring the marginal cost of adding a few
gallons of epoxy to a project the size of a Wyo, vs the cost of going
to home depot and getting enough tar (and fresh clothes) to attach
the bottom to the boat.
On the other hand, if things have reached the point where Jeff is
surface coating, sheating, glueing and filleting with tar, then I set
aside my point.
I don't know what the cheapest epoxy is, WEST costs me anything from
57-120 a gallon depending on volume, that is 40-80 in US dollars.
The US source prices should be lower. These prices are available to
anyone, but the lower prices are based on 62.5 gallon volume.
Someone mentioned that RAKA 5-1 is half the price of WEST, though
that doesn't help me much.

Yup, that's what happened. I've seen it on sale here commercially at $25
for a 5 gallon bucket. No mixing, no thickening, just trowel (notched) it
on, fasten, and go. My kinda stuff!

Interesting provenance.
The idea that the wood lifts before the cement does sounds familiar
from the last time I patched my roof. This is a minimal condition
for a glue, and applies to water used to assemble seasonal structures
in sub zero climes, and fish glue used to seal letters. It doesn't
mean the glue adds much to the structure.
I wouldn't want to bond to it with glass/epoxy, but if that isn't in
the plan, it might an interesting experiment.

George Buehler is the source of the idea, his concept was to glue multiple laminations together of
plywood, because the thickness required was to much for a single layer. He was looking for a cheap
way to glue large flat sheets together. I think Fritz Funk tried it and after letting it set for a
good long time, the wood lifted not the roofing cement. ATCO is the brand name used locally by
commercial fishermen, under the generic term "bear s--t". I think it would work fine for a Wyoming
bottom.
Fritz can correct me if I got his story wrong.

At a neutral axis, you don't need to buy the best stuff, and I am
