I molded a monitor into the dash of my 95 neon. It costed me like $10 plus the TV. I molded it in with bodoglass resin, then feathered it into the dash, which I sanded and primed until it was completely smooth.

Ok got a lil prob..

I have the dash now.. And it was painted silver.. What type of grid sand paper should i use to smooth it up a bit before i start to use the resin?

my guess would be 200. This will easily remove the paint, and give a good scoring to make the resin stick to, but not be too rough to rip the plastic up to the point where it would be a PITA to cover up. Make sure to clean it really well also, and possibbly spray an adhesion promotor to help the glass stick,or the glass will seperate from the plastic easily.

I'm guessing you'll be doing this in your garage??

Just a couple of pointers from my exp. Make sure you get a good respirator, cause 5 minutes of exposure to those fumes and you'll be on the ground, out cold.
I have no idea what the weather is like where you live, but if its too cold when the FG is settling, the resin may take a really long time to cure, warp, or may not even fully cure at all/
Its not fun having to peel off a semi hardened slab of fiberglass and have to start all over again.

Good luck, and make sure you post pics when ur done  ;)

So i don't start college till January so i am pretty much working on my ride all day as well as looking for work..

I got up this morning to check out the dash and wow it looks great so far.. I'm doing 2 more coats of resin on it then sanding it for aboout 3 hrs. Then cuttin out the dash part where my screen will be molded into.. Looks hella tight so far. Pics will come soon once i remember where i left my digi cam.

So the damn resin is eating away at the dash and bubbling the plastic now..So i gotta sand, sand, sand then spray paint remover and let it sit then sand, sand, sand, add more resin, sand, sand, sand then make the cut out for the screen to be molded..

Soo much fun!

theres another way of doing the f/g dash.. not the molding but to coat the dash..  at a body shop i work at they call it Gel Coat its not paint.. its 3 chemicals that are mixed together...  the guy i work with mix's it for me so i can never see what chems they use...   anyone know what i am talking about... 

Gel coat is just fiberglass resin you spray like paint, except it's usually colored. The chemicals are polyester resin, same stuff as f/g resin, MEKP (hardener), and probably a reducer. I've never done it before, but its not hard with the right gun (which is cheap).

Try adding more hardener and more heat maybe so it sets up fast, leave less time to eat the dash

A little late now, but I would have stripped off all the vinyl off the dash first and then fiberglass the dash. This would have given you better adhesion to the dash as well as it would not have bubbled the dash .
