The carpet latex does take a few days to dry that is if you can leave them hanging in the sun (weeks if you can't). But that isn't a problem for me.
The latex paint will dry faster and you can thicken it up with baking soda or flour (just like making gravy) but I like the look and price (8 dollars) of the carpet latex.
Here's a Big Lots 8 dollar skeleton I did by dipping paper towels in the latex glue and staining while the latex is wet. It's not great but I didn't need a great corpse because big rats were all over it
(edit) I read on another board that mask making latex is going up at least $10.00 a gallon by the 1st of next month. So if anyone is going to buy the mask making latex, you better get it soon.
