Glass Pro Stained Glass Lead Cement Putty Black 1/2 Pint (236ml)

Glass Pro¨ Putty is an outstanding fast-setting black colored stained glass cement designed for strengthening and waterproofing leaded glass panels. It cleans up easily with whiting. It's a ready to use oil-based elastic compound that is easily applied. It adheres tenaciously to came and glass, expands and contracts with weather, and forms a tough surface coating while remaining permanently elastic. Apply at temperatures above 4.5 degrees C.
