Absolutely as described
This is a unique product. It works well to seal up holes in electrical boxes with wire passing through. Easy to knead and shape. Not sticky to the hands but stays in place very well. Too soon to tell but seems like it will stay pliable and not harden. Bottom line a great product for sealing up those holes in the wall through out the house where plumbing or wire passes through.

easy to use and a must have for fending off the elements
A must have with outdoor electrical work. This stuff is easy to form into whatever shape you need to keep the outside where it belongs and not inside your electrical box.

I had high hopes but product doesnt dry hard enough
Product appeared old and was sticky on my hand skin. Finally, after shaping product and leaving it several days to dry, I found product to have hardened, but not hard enough. I could reshape product and it wasn’t a good seal-used around the sides of ducted diffuser. Back to the drawing board. Or, next time you cut your floorboards to install a diffuser for the ducting heating, make sure you know how to use a hacksaw. Try to cut diffuser housing spot-on or you’ll be forced to search for sealants that perform lower tham expected.
