I'm getting ready to start fiberglassing my door panels. On the lower part I'll be adding some speakers then the rest of the door will just be glassed. My question is will 1.5oz fiberglass mat be ok for fiberglassing the door panel? I was thinking of only doing like 2 layers of mat and then a layer of 24oz fiberglass cloth. Will this be strong enough? Or are there any other recommendations as far as the weight of the mat and the cloth?
Thanks in advance
