I wouldn't say stay away from durabak. It's really all in what you want/like. The durabak has a thick rubbery feel too it. It's too aggressive for bare feet. However, if you are building a fishing boat, i guarantee you won't slip on durabak, under any conditions. Durabak cleans up well with a power washer. If you are a clean freak, id say NO to durabak. It holds dirt and grime, but again it does clean up well. It seems to be very durable and will cover imperfections, so less sanding/fairing.
This is the durabak on my 23 :
The kiwigrip is a much softer texture, it doesn't feel rubbery at all. It dries to a more hard feel. As far as making it even.........all i did was blob it around on the area and then use the roller and went in all 4 directions. The directions say you can wait for an hour and then re-roll and it will "pull" it up more for a more aggressive texture. I didn't do that, i just rolled it then pulled the tape off, and let it dry overnight.
I think the kiwi will be easier to keep clean than the durabak. The price is about the same. I've had the durabak on for a year and we fish pretty hard. When it's clean it still looks the same as it did when we put it on. Either is a good product, but i give ease of use and looks to the kiwigrip. I think the price is about the same on both.
