The process of stailizing wood involves two ingredients, a resin and a solvent. The solvents are all flamable so be very careful. I am experimenting with different resins and solvents now and so far Acryloid B-72 is the best. I use a 2 gallon spray paint pressure tank and 56 PSI of pressure. I can tell you that Nelsonite or Min Wax Poly Clear Gloss are not what you want.

The cost is not cheap. Even the Minwax wood hardener is expensive. The reason I am doing it myself is that I have a lot of wood that can be processed, spalted maple, ash burl, highly colored boxelder, apple, plum etc. and the cost is shared by a friend.

A one gallon mix of B-72 & acetone solvent costs approx. $35. The tank, compressor and gauges cost ~$200.
