Red Devil Onetime Lightweight Spackling
This lightweight spackling is essentially the same as the other Red Devil product listed as number one, but doesn't have the color changing capability. I suppose there might be some applications where the chemical used for color changing could cause a problem. This product spreads easily, providing one-coat filling of a large variety of applications. Its water-based for easy clean-up. Like the Phenopatch product, this one can be used both indoors and out.
