Glue for MDF and enclosures

Thanks everyone.  I think I'll stick with the liquid nails that is made for MDF and a few other surfaces.  I used it to glue a couple small pieces of MDF to the metal of my truck and it is holding pretty well from what I can see.  It comes out very thick like cake frosting and it's an ugly light brown color, but it seems to have a strong bond.  Since it's so thick, I just applied the glue and set the wood there and pressed hard for 30 seconds or so.  I didn't have to sit there all day and wait for the glue to dry.  It just held the wood in place and was probably completely dry by the next day.  So when I build my amp rack out of 3/4" MDF, I'll use that glue to connect all the pieces and on the part where the amps will rest, I'll use metel brackets to hold a few pieces of the wood together for added strength.  I'm also going to wrap the MDF in fleece and glass it before it's all painted or covered in vinyl or carpet.  I'll probably put a layer of Maraglass over the fleece with resin too so I can form the exact shape I want and add strength.
