How to Make a Fiberglass Subwoofer Box

Step 11 11. Resin

Using the good mixture and the resin and hardener (as mention in step 4), take your cheapo paint brushes and start painting the fleece with resin. Cover the whole area, except where your sub will go, that isn't necessary to do. Saturate the fleece with the resin until it becomes soaked through pretty well, it will need to dry, but once it does it should be pretty solid.
