covering with epoxy/fiberglass
A friend told me he uses epoxy thinned 50% and paints this on .75 oz fiberglass clothe.
I've never tried epoxy to adhere fg clothe, is it easy to sand?
Is it a hard finish like resin?
Seems to me epoxy is usually kind of soft and hard to sand.
Then he fills it with a sanding sealer.
I'd like to hear some opinions about this.
TIA

I have always used Dan Parsons .6 oz cloth. I don't know if he still sells it. His method is to brush on thinned epoxy ( thin with rubbing alcohol 50%. Cover each side then give a second coat. THEN you need to do a lot of sanding with 80 (yes 80) grit paper. Sand back almost to the cloth. works for me.

I use West Systems epoxy unthinned with .75 oz cloth. I squeegee the resin into the cloth with old business cards smoothing the cloth down and distributing an even layer of epoxy the thickness of the cloth as I go. Light sand with 150 grit sand paper then spray pretty heavy coats of sanding primer to fill the weave then finish wet sand the primer for painting. A nice lite finish

Although these instructions were written around Z-Poxy, we have also used WEST Systems with excellent results (it's a stronger resin).

glassing
In the process of glassing a Bobcat now. I am using the West System.
105 resin and 206 hardner. With the 206 resin you have plenty of working time.
This is the first time I used this product and it works great. No thinning needed. I lay the cloth (.75 oz) on the surface then use a little 3 inch paint roller the spread out the resin the come back with the credit card and squeegee it out.
Do one side at a time. After both sides are done, come back with a second coat of epoxy only.
Home Depot sells these little rollers in the paint dept. It has a real short nap on it

thinning with rubbing alcohol
The comment about thinning with rubbing alcohol----I have thinned a lot of epoxy resins with rubbing alcohol and it works great.....but.....be sure it is the 99 % stuff and not the 70 % blend. They use oil to cut rubbing alcohol ( like lanolin ) to make it easier on the skin. The oil makes for a good ' fisheye ' look to the paint.
Recently I have started using a tip I read in the BVM site. I am now using acetone...I think it is working even better...
Spraying on primer to fill the weave and sanding it down has always been an extreme pain to me, so I started using the BVM pinhole filler, after the first sanding, to fill the pinholes and weave. It does a pretty darn good job too......it only takes a minimun of primer this way and one heck of a lot less sanding.
