Methylethylketone (MEK) works, but you'd better know what you're up to. It may not be available in the corner store these days, as it was 20+ years ago. Best to work under an exhaust hood with solvent gloves. I also use the NBC filters in my respirator. Make sure you read the applicable MSDS before you proceed.
Acraglass thinned to the consistency of water makes a great sealer inside a stock. There are probably MEK substitutes available; I'll be trying acetone next time. Some of these super-solvents may attack the binding material used in laminated stocks.
