Dura-Tuff can be bought for about $25.00/quart on the web. I can't remember where I bought mine, but that was about the least expensive last August. There's a link over at the QajaqUSA forum from around that time.

I like it because you can recoat in about 1.5-2 hours, so I was able to coat my SOF in one day. ZAR requires a day in between coats, as I recall.

Dura-Tuff gets less glossy if you use more pigment to color it. I kept mine very translucent, but I have seen others' with more pigment that begins to look like paint. Mine is glossy because I put 3 coats of clear over the 1 coat of pigmented.

The downside of Dura-Tuff is that it is solvent based, and it is noxious solvents. High quality organic respirators are a must, even painting outside, and it will continue to off-gas for at least a day. Leave that puppy outside until well dry! (My house stunk that night and the next day!)

I put 4 coats on a 17.5' kayak, and I used about 2.5 quarts. I mixed up 1 quart for my base pigmented coat, but only used 2/3rds to 3/4rs of the quart. I would have put another coat of clear on, but I had run out of time, and so I had some left over.

For your child's kayak, you wouldn't need 3 quarts for sure.
