EzTex also cures without shrinking, meaning I had only to fill the holes once and scrape off the excess before cure as opposed to multiple fillings and time spent flattening an overfilled repair prior to refastening. EZTex is white, is paintable and can be used with fiberglass,metal or wood. It cures in 24 hours at 50-degrees, and is said to cure in5 hours at 70 degrees F and 3.5 hours at 90 degrees.
