2003 Ext. cab fiberglass

May it will work now

I am not sure what those shadows are on the side

here is the front view and you can see the place holders for the amp rack that holds the polyester down

here while waiting for the resin to dry we cutout the rings for the kickpanels

here are the rings glues together

If it is cold you will need A LOT of MEKP, or harderner.  Where did you get your resin?  They should have individual packs of harderner you can buy.  I will use both the bottle's of harderner that come with the resin plus sometimes 2 more when I am glassing during cold weather.  I am sure Wal-Mart carries the individual MEKP in the area where they sell bondo and stuff.

Also, this is a HUGE box.  You will have to sell your truck to afford all the mat and resin you will have to use. I am going to suggest Cabosil (Aerosil).  It is a powder substance (kinda like grinded up mat) that you mix with resin and it turns into a thick substance (like peanut butter).  It takes about 80% less time and resin, and can get your enclosure as strong if not stronger than multiple layers of matting.  Not to mention, it will leave you with a fairly smooth surface to prep on the outside, because cabosil goes on the inside of the box.  Good luck, and the box looks great!!

thnx guys, I have already bought more than enough mat 90 feet by 4 feet I will probaly need more resin they gave me 1 bottle of hardner and there are directions on the rsin that say 1 bottle of resinn per gallon of resin, it did say you could use more if it is cold.  I will go buy some more tomorrow. Thnx I saw another thread about cabosil I will go check it out. 

Are you going to secure your box into place.  I know that because of the size of the box it may not seem that it will move but you might want to take that into consideration.  I know that it's kind of late to think about this at this point but if you decide to screw it down so that it wont slide in case of an emergency you can probably do braces on the side of the box.
