What's the shelf life of an opened bottle of Genuine Oil by Birchwood Casey? I believe this product is a 50/50 mix of tung oil and solvent.
My first bottle definitely changed after 3 months of use, and I've noticed the second bottle isn't the same after 45 days. Situation - foil seal is opened only w a pinhole, but the cap doesn't screw down tight, it's loose. It's seems like the bottle is congealing inside. Has to be shaken vigorously to free up the contents so oil will flow. I don't think the new bottle was like that.
I called B. Casey's help line, and even got through to someone. Unfortunately the person wasn't knowledgeable about the product at all. They were polite, but couldn't provide specific information.
