U-Beaut Hard Shellac Expiry

[EagerBeaver71]

I just found a bottle of U-Beaut Hard Shellac, its been sitting in my tin shed under a load of newspapers for some time. The expiry is 05/2021, should I chuck it out or is there a way to know if its still usable?.

I myself wouldn’t use it as it is over a year expired. But you can dilute it 1 to 10 or so to make a sanding sealer.
