Fleece has always worked well for me. It stretches well and is strong enough after it sets up that it doesn't warp much when you lay up your reinforcing fiberglass.

ive used fleece but i never totally absorbs the resin, so the inside still feels soft. Then it wont stick to the subring well. do i need to use microfleece?

i always use the fleece but i would try spraying an adhesive onto the subrings and/or fold the fleece in the sub hole and staple it.. you can still cut the excess of the fleece off.

sounds...I'm also interested to know more about the mold fabric since I'm not thrilled with the texture of the fleece after the resin goes on.

pureRF...I had the same prob with getting the resin to fully saturate the fleece. I found(from someone with 20yrs of fiberglassing) that I could thin the resin with up to 10% acetone(I use 2oz in 24oz of resin) and it doesn't affect the set up time or strength...just makes it a bit more liquid so that it soaks through the fleece better. Also, the tighter the fleece is stretched, the easier it is to penetrate. If you still have trouble with it not sticking to the ring, try making the top ring out of particle board instead of MDF...much more porous.

There are tons of different weighted fleece that you can get. I use the lighted weight fleece that I can find. As well there are different types of fleece with more or less stretch in the fabric. As far as sticking to the trim rings, what you can do is take a mini DA sander and use 120 grit sand paper and sand the smooth surface rough to better adhesion.

Velocity...Thanks for the DA idea on the MDF ring. I'll definitely do that on the next one since I much prefer routing on MDF over particle board. Got the particle brd idea off another forum and it worked fine so far(fleeced and resined), but I think I'll add another ring of MDF before I start layering the inside...just to be sure! An inch and a half of mounting surface can't hurt anything. Between my new router and my home made circle cutter, making more rings is not the grief it used to be.

I have used mold fabric before nothing compares, considering it was designed with custom fabrication in mind, now i use it for all applications.
