Re-Sealing that can

I needed to varnish a piece of wood, and as usual, the cover of the can was stuck so strongly (had been previously opened) that I had to damage the seal to get the cover off. Faced with loosing the rest of the mostly full gallon of varnish, I pulled out the roll of aluminum tape again, and was able to seal the top.
Results:
I opened the can three weeks after sealing it, and the varnish was perfect, with no skin on the surface.Looks like it works.
