Seeing the bottle of WS Latex Rubber reminded me of an experiment I did this week.
I recently bought some sea foam to add as branches on trees and the best way of protecting them seems to be dipping them in liquid latex (Geek Gaming video). Every type I looked at was costly but my local game store had had the WS Latex Rubber on sale so I bought that.
As you show, it is quite thick but I poured some into a tub, added water, mixed it up and dipped some sea foam. It works but requires around 3 coats before one can handle it without breakage.
