Well, it was 5200, mahogany color (at least that's what the label said). I used it to fasten Minicell bulkheads. I put a nice even bead and feathered it out. After letting it cure a few days, I noticed that instead of the nice smooth bead it had shrunken into the joint which was now a crack. And the joint leaked. I don't use the stuff any more after that experience. I don't have this problem with polyurethane caulk, and it costs half as much, does a very good job. just the facts. Grant Goltz
