Is the carbon cloth expensive?


Depends on how you figure.

The stuff I'm using is about 4X the price of FG cloth of
about 75% teh strangth, and about 1/3 the weight. So it
doesn't cost that much more by strength, but you're buying
weight saving.


.... What is black, the cloth or resin?


The cloth

The cloth you are going to trim looks just like fiberglass cloth.


That's the biaxial kevlar which is almost like bridal veil.
Some of the pics also show the peel ply which went on too
late & too slowly over the outside to hold down the
laminations. The resin was curing much too fast even though
it was kept in a refrigerator.

I've never worked with carbon, is it just like working with glass?


Pretty much, it's actually easier to handle in some
respects. The big difference is that you have to do
something to tack it down or it floats on the resin, and the
dust & spinters are more hazardous to your health.

BTW I did not get as much done as I thought. That stuff is
really tough to sand and there were more gaps. Damn wasted
material & time!
