A-Mac, I haven't used any concrete sealers yet, so I can't say. Seal-Coat is designed for dipping jig heads. A friend turned me on to it, but I have basically no experience with it yet. I glued a twisted wire in a piece of balsa with it, and it seems strong. I didn't test to failure, but I pulled hard enough to slip the drag on any of my reels, and it held. It is about the viscosity of thin syrup. From what I saw on the surface of my raw piece of balsa, It appeared to penetrate the wood a bit. It could also prove to be a good balsa sealer. I don't know how the durability would be as far as a crankbait finish coat. The low viscosity would lead to lots of dripping/running, I assume. Anything coated in this stuff will probably work best on a wheel. In time, I'm sure I'll find some good uses for it.
