If dried, and kept dry!, I think it would work O.K.
If it happened to get wet here in Mich. the mold would be bright green in 3 days. I have to skip that one.
Touching on stains, an old guy we used to talk to near our fishing spots, used pork blood, and mineral, lemon, and linseed oil on his refinished & homemade rifle stocks! Orange, pink, red, to deep red/black. Always sitting on his porch polishing. Dunked in a bucket of it, used small 2" spot on a white t-shirt rag for upkeep. The stocks didn't smell & looked like a dark sunburst guitar.
