Hopefully the Action doesn't have rust on it if it still has the old lacquer on it.

To remove the old lacquer, mask the wood with blue painter's tape. (It won't harm the wood finish when you remove it) Use lacquer thinner or acetone with cotton balls/cloth to remove the old lacquer. For near the edges next to the tape, use "Makeup Applicators", which are Q Tips with one pointy end. Carefully use the pointy end for at least the first 1/4" next to the wood.

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
