GBProduct performance was very good, instructions lacking Product performance was very good. However, design function of the caulking style tube was not. A normal tube is empty when the charging rod is fully deployed inside the empty tube. Without knowing the charging rod is fully deployed at 3/4 of its normal length caused considerable delay and improper injection of the polyurethane foam into the concrete wall.
