I don't recommend Dyna-art I didn't like their product although this has
been some time ago that I used it.
I would recommend

Pnp blue it stores for years if you don't scratch the traces.

If someone would like to try Techniks PNP Blue I can sell you the sheets.
Contact me off list.

A Tshirt press may be ideal, but very expensive. You could send out
to have an awful lot of boards made for the $500 to $1000 it costs
for a good Tshirt press with adjustable temp and pressure.

That said, I just picked up a small double sided grill, like one of
those sandwich presses except it is flat on both sides.
