The same company produced a "Wood Dough" which, while great for household use, was soft and shrank. This may be the current DAP product. What happened to Durotite, and what do they use to fill gaps and screw holes in the wind tunnel these days?
Durotite sounds familiar, but I can't place it. Maybe you are thinking about Durham's Water Putty? It is a powder that you mix with water and it makes a putty that is fairly nice to work with, tenacious as hell, sands and finishes well, is very hard when cured, and shrinks very little. I usually use bondo as I don't want to wait for drying. I can work the bondo in 15 min.
