WiLL, why don't u do this way.

Glassing the MDF mounting to the cover. Mean while back that up with a wooden frame into the door's metal body (kinda like a tripod) That way, you'd only be glassing the top, while have the back support of the metal frame? That's something I'd do when I try out the 6000 series on my daily car. Until I'm success, I'll do the 6500s on the other car

I think kickpanels are cool, but they take up too much space, especially in a Honda/acura family (besides the BIG boys of course).
