I'd imagine that there are multiple products out there for use on stabilizing woods, but the one I use is "Clear Penetrating Epoxy", also sold as Restore It (same product, same company). It changes the cellulose of the wood, dissolves the sap and oils-- strengthening and reinforcing it. It is a solvent based product that is about the viscosity of water, so it penetrates really well. The product I use is made by Smith and Company in Richmond, CA.
Yup Owlbait, I'll be there with the new takedown longbow and with any luck, one or two of the new one piece hybrid longbows as well. Looking forward to seeing you guys there.
