Trying to mold my doors...:((((

Greetings all, 
I just discovered this website and it looks like a great resource for novices like myself. I've been trying to mold my doors but have run into repeated failures.
I've posted this previously on compositescentral.com, but was hoping to get some feedback from you all.

I cleaned my door and flanged it, then sprayed several coats of PVA (next time I will use mold release). I then applied gel coat with a roller and brush. The temps were low when I applied the gel coat (approx. 49* F but I mixed extra MEKP and have had success even when allowed to set at -10* F).

Here is a pic of the door after the gel coat was laid down:

So I when I checked on it this afternoon (approx. 16 hrs later) I noticed a new problem I've never seen before with gel coat...it pulled away cleanly from the plug in some areas. Would this be due to nonuniform thickness??

Hey BlackNDecker,

Have you finished building the door(s) yet?, I'm curious to know how you have/will lay up the carbon for the thinner window frames.
