Varnish always comes in metal cans. Is that because it is light sensitive or oxygen sensitive? Or it is just traditional?
I am about to make up some wipe on, and don't have a metal can. I took a white plastic soap bottle and spray painted it brown. Stored in a room that gets no sun light, is that likely to be adequate? If not, where does one find a metal can?
I probably have stain I won't ever use; if it comes to that, but it isn't really user friendly.
