To give credit where credit is due, I would like to recommend two vendors
that I have recently had transactions with. Both are above average in that
they actually answer your questions, have great prices, and courteous
service.

If you need cordage, try
www.cbknot.com

They carry the Samson line and several others as well as a small selection
of hardware.

If you are in the market for epoxies or polyurethanes, try

www.epoxyproducts.com/marine.html

I have no affiliation with either of these firms other than as a very
satisfied customer.
