So I've got the plans that I need to build my sub box, and my plans are, I'm gonna build it out of 3/4"mdf, then cover it in fiberglass. How hard will the fiberglassing be? Its gonna be on all flat, smooth surfaces, but I've never done it before. And I hear the resin smells real bad so I won't be able to do it in my basement? Any advice or tips would be awesome!
