Beleive it or not, we do alot of fiberglass in this small TN backwoods, no stop light, one save-a-lot havin, cow infested town
. Anyways, fleece is a decent material to use rather than paying unbeleivable prices for other mold making materials. Just a few tips for ya.
1.) Watch your resin use. Most people have a tendancy to pour it on. Too much resin makes your part really brittle.
2.) Watch your catalyst mix. Most people have the mindset that if a little is good, more is better. Too much catalyst and at best you're going to kick off your resin way before your finished laying up the part. At worst, you'll ignite your glass and have a dandy little fire.
3.) If you're making the part for show quality, you will have to make the mold first! Your mold will be the reverse of your part. If you're only interested in creating an inclosure to carpet or cover, the job will be so much easier
4.) Have fun and be careful around catalyst and acetone.
If ya need a hand or have any questions, feel free to email me, I'll be glad to help you out anyway I can.
