With the wealth of knowledge here, this has probably been covered... but I will venture on, having not found this possible alternative yet.
This past week, I spent quite a bit of time at one of our plants, where we make gearing. During a tour I encountered the smell that was unmistakeable, I smelled liquid alox. Never paid attention before, but now that I am casting, my nose perked up and the search was on. Turns out that the fininished product is coated in this black alox for long term storage. Its like a semi tacky black wax when dry. Smells just like LLA.
Anyone tried anything like this stuff?
