The rear deck is a little too boring for me so I fabricated one. Using the original — or rather the one that the last owner made which was nothing more than a piece of plywood cut to shape with black carpet glued to it — I made a template. I then mounted rings I had cut out with a router and the surface-mount tweeter cups to the deck.
Using yellow fleece (the kind you can pick up at any sewing store for $5 a year) I wrapped the rear deck using spray adhesive to hold the fleece to the underside. I like using yellow because it gives great visual indicators when applying the fiberglass resin. If you use enough resin (for the rear deck about a quart and a half is about right) you won't need to use any filler. Unfortunately because this was the first thing I had glassed in about a decade I made a mistake during the fabrication process.
Once the resin set I had a lot of body work to do. If you're going to do any custom fiberglass and find yourself needing to use body filler, do not use standard body filler. Get duraglass (or something like it) which is essentially fiberglass body filler. It's hell to work with, does not set nearly as forgiving (resin/hardener ration and heat play a huge role with this stuff) as normal body filler and gums up pads unbelievably fast. But it flexes a lot when it's dry and you don't want these things cracking down the road.
In the end though, it turned out well. It's not too gawdy and plays well with the rest of the car.
