newbie fiberglass projects done

my first project I made a box for 2 10" Alpine woofers w/ a spot for an Alpine amp. it turned out a little wavy. i think that was b/c of the thin walmart fabric i used.  My lastest project was a rear deck for my friends Nissan Sentra. I'd rather experiment on other peoples cars before I do mine. this one turned out much better than the box b/c I used select products mold cloth. Thank god it fits perfect. It is going to hold a Fusion Jonah Lomu componet system. Take a look for yourself. Let me know what you think and how to better myself. Neither of these projects are completed but my part is done. I'll leave the painting to the body shop.

what did you use to make the mold for the alpine box (im assuming that that is the red one in the pictures)?  Its got a nice design--i really like it.
