The two messages appende below are excerpts from an exchange on skin building and coating from the Baidarka mailing list (reproduced with the expressed permission of each author). The debate on the pros and cons of polyester fabric (Dacron et al) compared to various types of nylon continues. This goes for coating also. Most would cure too hard for folding boat skins, but Hypalon and (liquid) neoprene are definitely viable options (again, see Peter Chopelas's North Alaska Retrieval Kayak adaptation for an example using Hypalon). The Baidarka ML archives are a treasure trove, too.

I kept the room at least 65 degrees and the nylon loosens when you apply each coat. This isn't surprising since the polyurethane is water-based. I will get back to you after it is well seasoned. I'm going to keep it in the warm shop for another four weeks before launching (Winter Solstice!) JF -----Original Message----- From: wayne steffens [mailto:[EMAIL PROTECTED]] Sent: Sunday, November 26, 2000 12:10 AM To: [EMAIL PROTECTED] Subject: baidarka getting closer We've got the main seam sewed on both the front and the rear decks, and sewing around the cockpit coaming is 95% completed too. As I've mentioned, we've been misting the nylon and sewing it snug but not overly tight while damp, and then it shrinks to near perfect (whatever that is) tightness when it drys. I keep the kayak in my heated garage. While I was gone for a few days the garage wasnt heated, and the skin was a bit sloppy when I returned. I was surprised at the difference. Its nice and tight again, now that the garage is heated again. Probably one or two more evenings and it should be ready for sealing-all we have to do is sew down the flaps along the deck and touch up a few spots. I presume when I start coating it with polyurethane (I plan to use water based), that the skin will loosen a bit when its applied. Will it reshrink again as the poly dries, or will the drying polyurethane "fix" it in the looser position? Or is it all a mystery?
