Zar should be available at pretty much any hardware store or home center.

There are some other things to consider here, though. Zar doesn't really stick to nylon, wasn't designed as a marine coating, and isn't flexible. It will crack, and get abraded pretty easily. If you aren't sure you love this boat enough to keep it the way it is forever, then it may be a good choice, because it's pretty inexpensive and it won't hurt so much to cut into it if you decide to make some changes and reskin it.

Before you buy, you should check into some other options.

It is expensive, but I'd recommend Coelan marine coating, which is distributed in the US by Premapro. It's designed to be used on flexible fabric objects like inflatable boats, and will stick to nylon, it's really flexible (300%), very abrasion resistant, and lasts a really long time. It's 1-part, so it's just like brushing on paint. It dries pretty quickly, and only needs 3 coats.

Also consider Spiritline's 2-part polyurethane, which is available from Skinboat School in Anacortes, WA. It is SUPER tough, but tricky to apply. You have to use a spreader and work pretty quickly and in small batches, but the bonus is that if you do the hull early in the morning, you can do the deck in the evening and be completely done with the coating in a single day. It takes three coats of this stuff too, but you do all of the coats at once without stopping in between. This coating is pretty expensive too.

One of the largest drawbacks is that both of these products are available from only one supplier. In the case of Spiritline, they cook it up there, and in the case of Coelan, it's produced by a German company that's been around a long time and offers a range of high-end coatings for quirky applications. Customer service with Premapro is exemplary ++, though, so that somewhat mitigates the fact that they're the only distributor.

Both of these products are expensive, and if you decide you want to change your boat, it really hurts to take a knife to the skin. (Experience here) If you go with Zar, because of cost or whatever reason, be aware that Coelan is intended by the company to also work as a coating over cracked finishes, so conceivably you can paint it right over your Zar.

There are a lot of people who have traditionally used Zar, and they can advise you of their success. I did spiritline the first time, and wasn't happy with it or my chine locations, so my skin is about to come off, and I've got Coelan waiting to recoat the new skin with. You can check the Qajaq USA forum for more info- there was just a thread on Coelan this past week, and there's always stuff about Spiritline, even as a part of the Coelan thread.
