Duraglas Fiberglass Filled Filler 1 Gallon

Years ago (40) I used Duraglas for auto body repair. I have a project in Florida and was looking for a product to secure wood posts to a concrete pad. The old metal post anchors had rusted. I found that Toolsource sold Duraglas. I ordered one gallon at a very good price and it was delivered in record breaking time. Have not used it yet, but I'm sure it will work. I was surprised that Duraglas was still made.
