Glue for MDF and enclosures

I'm building some amp racks and other structures similar to what Alpine did in a couple of their demo vehicles.  What glue should I use to glue the pieces of particle board to each other and to the metal of the truck frame?  I plan to glue pieces of MDF in certain places to make a frame and then stretch fleece over it and staple that in place so I can resin it, Maraglass it and sand, then apply Rage Gold and sand before I remove it from the truck and have it professionally painted.  Alpine refers to their glue as "Super Glue".  But if they're talking about the name brand stuff, it's like Krazy glue I think.  It comes in two tiny tubes for about $3 and I'd need about $500 of the stuff to finish everything I'm doing.  Should I buy a hot glue gun and use that?  Or is there some other glue like krazy glue that's incredibly strong, dries fast, and comes in large quantities for not too much dinero?

Please help a noobie out!!! Thanks :)

Plan, Research, Do

Jet, Zap,Hot stuff are another couple of brands of cyanoacrylate glue.  Any of these works great, I prefer the gel type versions.

I have used heavy duty liquid nail thatr is the name of it, the trick is the prep work if you try to apply it to smooth painted or bare metal it will not work all that well unless it is in a crack. So just take some sand paper and score the metal bfore you apply and you will be alright.
