I have some lacquer in a gallon can. It was pretty clear but when I open it up (month later or maybe much longer) it's amber colored. When I put the lid back on a gallon can I turn it upside down to let it kind of seal itself so it does seem it got air in it.
Question does it sound like it's life is over. I poured a little thinner in it hoping to add some val ital solids to it. You think it's still usable, but will give off this amber color. or give to the wife for hair spray?
