Why in the world would you put a laquer finish on a gunstock, the first time you have the stock in wet weather the finish will turn a white milky color, laquer and poly varnish finishes are for furniture and kitchen cabinets.
A gunstock requires an oil finish with hand rubbing the finish between coats so as to create as little biuld up of finish on the stock as possible, the finish is suppose to be in the wood not laying on top in multiple coats. Any gunstock that is finished with a laqueror poly varnish in multiple coats will get scratched and dinged and will have to be completly stripped and refinished to repair the scratch, an oil finish is in the wood and can be easily repaired with some steel wool and a little of the oil finish.
