the one coat of resin that it takes will be stronger than one coat with fleece. the fleece will soak up alot and youll have to put at least 3 coats on it just to make it worth while. anyways a quarter of an inch thick is usually sufficient in making a sub enclosure

Depending on the shape you can use a layer of Coremat. US Composites sells the 4 mil for $8.75 a yard. This is the same stuff that Select sells for $19.50 a yard. You'll want a fiberglass roller to eliminate bubbles. Coremat is thick and doesn't bend like mat does. It's a good bulking agent to save a few layers of mat.
