I made some experiments with my roofing cement I am not too impressed with it. The biggest problem is that it solidifies too long. I wonder if anyone knows of any sticky, fast-drying, heavy, non-toxic, elastomeric coating that can dry “in depth” (let say 1-2 inch) and will be liquid enough to be mixed with sea sand. I was considering different versions of 5-pound close-sell foam but it look like what it dry it too dry for my application. I would like my coating still to have some rubbery feel, not too rubbery as it will overtrump my horn. I would like to be able to wary the level of horn damping by the depth of external coating sure. I can’t be certain how much elastomeric coating would be too much. I would like do not create a completely dead horn. I would like horn to breathe with own resonances but I would like those resonances to be subordinated to the driver and do not be systemic. I think if I apply the loaded elastomeric coating in more or less chaotic locations then it would break the permanence own harmonics of my horns as a construction devise. At least this is a hope…
