Frequently Asked Questions

What grit of steel wool should be used for smoothing an AK-47 stock before applying polyurethane?

For smoothing an AK-47 stock before applying polyurethane, use 400-grit steel wool. This grit is fine enough to smooth the wood and remove imperfections without causing significant damage, preparing it for an even finish application.

How can I prevent bubbles when applying polyurethane to a firearm stock?

To prevent bubbles when applying polyurethane with a foam brush, avoid excessive back-and-forth scrubbing that can create a suction effect. Apply the finish smoothly and evenly in one direction to ensure a bubble-free coat.

How many coats of polyurethane are recommended for an AK-47 stock refinish?

The process described involves applying multiple thin, even coats of polyurethane. The video specifically mentions applying four initial coats to build a base, with the understanding that subsequent sanding and buffing will refine the finish.

What is the purpose of using a tack cloth after steel wooling a firearm stock?

A tack cloth is used after steel wooling to pick up any fine steel wool remnants and dust that may be on the wood surface. This ensures a clean application of the polyurethane finish, preventing imperfections from being sealed into the wood.
