Have you ever seen those beautiful wood table tops with 1/8 inch of perfectly clear epoxy on the top. Well maybe that type of product is just what the doctor ordered.
You said you had 0.1 headers on one end of the boards. So tie a string to one of the male header metal posts…I’m assuming they are male.
Then mix up a very batch, but instead of pouring, suspend your boards in it, like making candles. Don’t let any of the liquid get near the headers. Tie the free end of the string to a clothes line and let the wet boards set thoroughly.
I would assume the product is thick enough to put on a nice even coat.
Let the first coat dry…and repeat the whole process as many times as necessary to get the thickness you want.
I wouldn’t think it would have any adverse electrical consequences…but I don’t know.
OK…here is the product…EnviroTex Lite Epoxy Resin. It is…very highly rated at Dick Blicks Art Supplies. You can get a 8 oz. size for about $9 at Dick’s online. I’m sure it is probably very clear…and very workable.
I tried to post a picture…and link to Dicks…but the forum software says “I can’t post links or pictures”.
I just registered for the forum an hour ago…so maybe I’m not allowed.
Anyway, if you try it…please report back as to the results.
I think it is something a lot of people may like to do with their board projects.
