Gloss finish on dash

I'm going to be working on a custom stereo in a Porsche 944.  Since the original dash is cracked, the owner bought a molded plastic dash that will replace it.  But it is rather flimsy and he wants it to have a gloss finish when done.  So my question is, would you guys recomend adding a couple layers of glass before the body work?  I'm afraid that the glass will effect the fit of all the trim pieces when done.  I had this problem on my door pannels, and I only added one layer of glass (1.5 oz mat).  Or do you guys think a layer for Duraglass will be strong enough?  I may also re-inforce the larger areas underneath with some fiberglass just to be sure.  I figure gluing down some backstrap and then fiberglassing over it will provide enough rigidity.  Please let me know if you guys have any suggestions or tips you have found helpful.  Thanks!

Hey, thanks for the response.  The original dash is actually cracked, so the owner bought a flimsy molded plastic piece shaped like the dash that will be fiberglassed.  I should probably remove the old dash first and check for fit, but they drive that car around. 

They actually have two 944's.  One is a 944S4 with a race prep engine.  I get to do different installs in each one.  They just bought some new front bumpers as the old style is kinda ugly.  They also just re-did the enterior upholstry and gave them new paint jobs.  I am just finishing up a 928 right now.  You can see pics of it and some other fiberglass work I've done/helped on here: http://www.sounddomain.com/memberpage/304268/8

Here's a picture of the pods on the 928 almost finished.  They just have to be color matched:
