Yeah man sounds pretty good. If I were you I would look up some pics of door panel installs on here. Get some ideas and plan, plan. Also when your making a mold and doing any fiberglass work do not take it off the door. The panel will not fit the same way when you put it back on if you take it off while the glass is drying.

hi.  actually  i just finished my attempt at door panels from scratch.  i just posted pics on here.    i started with just the steel door, and the window motor, a blank canvas like you have.  then i taped EVERYTHING off as is on the door, and applied foil, then i glassed.  after i had a couple layers i peeled it all off and i had my mold.  from there you can do anything you want, as long as the door still closes.  just make sure you do a good job planning your design.  the parts i had the most trouble with were,

where the door met the dash when it closed (making sure the panel was thin enough so the door closed before the panel hit the dash) 

where the panel went around the door lever.  mine currently is not finished but it will be soon, if i would have planned properly to make it look like the stock trim piece did i wouldnt have to be re-doing it.

and the toughest part might be at the top op the door panel where it makes a 90 degree bend to make the top of the door panel, where the window glass comes up.  on this part i would suggest doing almost exactly what the factory panel did, because, in my situation there isnt much else one can do.    hope this helps,

i actually have tried fleece before and i thought it was too thick, it felt like i used way too much resin on it.  almost excessive.  so i tried some felt this time.  its a little cheaper.  i bought it at wal mart.  also, some people use grill cloth, and the guys at Alpine used speaker box carpet.  they say it is un backed carpeting, which i believe is speaker box carpeting.   really you can use any fabric that is slightly stretchy and absorbant.      

hey- when you get ready to attach the MDF to your fiberglass mold, tell me how you do it.  i have not had much luck with this step before, so when i made my door panels i cut a piece of felt the exact shape of my piece of MDF and soaked it in resin, and used it as a huge piece of glue, like a sadwich to attacht the MDF,   just let us know how this all works out for ya.
