These are AMC coasters. They were laser cut and they need a couple coats of lacquer.

Step 1: Items Needed

You will need your material, steel wool, brush, and lacquer.

Step 2: Steel Wool

There is residue from the laser cutter. To remove the residue, you need to use steel wool and go with the grain until the residue is gone.

Step 3: Brushing

When the material is ready, you will brush lacquer on the material. You will have to wait 2 hours, or however long the instructions say on the can. Then you will apply the second coat. Once the second coat is dried you will have a nice finished product.
