does anyone ever treat there stretching boards. i noticed a few of mine are starting to get a little humidity mold growing on them and was thinking about water sealing them. Didnt know if that would cause any problems or not though with leather-in critters? Also thought about laquer to but what ever is easiest is probably what i will do like a thompson water seal or something.

I seal them with spar varnish when I first get them. I put a coat on then let it dry,and each board gets three coats before there ready to use.You may want to sand them a little between each coat,just a real llite touch sanding. I also give each old board a new coat before the start of each season,this I feel prolongs the life of the board,plus they just look sharp when there done..................RT

laquer really isn't a sealer stain paint would be also try using linseed oil we use it on alot of our outdoor products just give it 3 heavy coats 3 days apart it will not go bad before the stretcher is bad

Mine are treated with coon grease, mink grease, fox grease, yote grease, ahh heck, you get the picture.

we are still useing the same basswood coon boards my dad made back in the early 70,s , had to trim them down to 7" but no sealer on them .

Wipe the mold off and use them. Ain't never sealed a board in 45 years of use. coongrease etc does a fine job and the mold don't bother a thing if you wipe it off.

No sealer for my boards.

I rub my boards with paraffin each year. Not so much for mold but to make sure the hides release easily as most all of mine are leather-in furs. The edges of the boards are the most important and the top of the head.
