do i need to use mat with every layer?

I dont know if this is a double post, i tried to search around, i was jsut wondering how many of the layers should have the fiberglass cloth or mat in them. and if it is that big of deal if the inside of the box is uneven.

The inside shouldnt matter if its uneven. Yes you have to use fiberglass to create a layer. So each one fiberglass is used.

What are you trying to build?

If you are trying to build a box, here is some advice.

The layers you lay down should only be made with cloth soaked in resin. Keep this in mind...The more resin you use, the more brittle your final result will be. Here is a good procedure for laying your mat...

-Lay out a large sheet of tin foil on a flat surface
-cut your mat into small squares ranging from 1.5"x1.5" - 3"x3"
-Properly mix your resin and hardner
-Use a 1" wide paint brush (get yourself a butload of paint brushes, use a new one everytime you make a new resin mix)
-Spread some resin on the tin foil
-Lay a square of mat down on that resin
-Using a stabbing motion, squish resin into the mat till it almost looks transparent
-Peel it up off the tin foil and using the paint brush, dab it into place in your car, or onto whatever you are reinforcing, making sure to get air bubbles out.

Doing this will leave the excess resin on the tin foil, not puddling up in the bottom or your project. Your box will be quite strong after about 5 layers. It might take longer when using small squares, but the reward is greater because you'll have less air bubbles and an extremely strong enclosure.

thanks guys, i am almost done with the box (its going to fit in the cargo wells in my 04' dodge quad cab) here is a pic of what i have done so far, i plan on putting a flat MDF pice that i have already cut to shape on the top. any ideas on how i should
attach the fabric to cover the top to the fiberglass, i was thinking about glueing small wood strips to the actually fiberglass so i can staple and stretch the fabric to them.
thanks

what kind of subs are you going to be using? I have a friend that wants to fiberglass his ram the same way but is
not sure of the airspace

I am using two 12" RF Punch stage 1's but they are not hitting that good, i would suggest getting something that handles at least 200w RMS
