Does it go off? I have 1/2 a tin from last year and was going to finish it off this year, maybe mixing it with the new stuff. Good idea or should I chuck it?
I've mixed old with new in the past, to no visible detriment. I'd have thought last years should be fine.
I think they have a reasonable shelf life. Let's face it, at the prices they charge, you wouldn't expect a brisk turnover..... /forums/images/graemlins/smile.gif
No bother. I always keep a bit back every year to fill-in after the cradle prop's are removed the rest goes into a jar in a cockpit locker for touch-ups and the following spring any that's still there gets mixed in with the new.
