I used this to make molds and to line a water-working stream. It is easily applied and removed from the mold source and easy to apply to the stream. Dries within a couple hours. Be sure to use 3-4 layers if you use it to line streams. Directions suggest to add gauze in between layers when making molds. It really helps

you can copy anything with imagination ,tunnel portals, stone walls, buildings, cobblestone roads, diarama bases,ect. excellent product for railroading & military diaramas.... I use 5 coats not 3, 30 min to hour each coat to dry then let set to 5 to 7 days for hard sharp lines...to clean water is, but gas or thinner is much better if you want your brush to be like new again,,, my experience with product has been very good, I have many molds which I use over & over on my train & military layouts.....this is the product of imagination......have fun...

Product did not perform. Appears to have been expired, (consistency of the latex was that of a heavy paste). Was expecting a more fluid product.
