Thick-Skinned varnish


One thing you can count on when you save a half-used can of varnish is that the contents will be skinned-over the next time you open the can. When this happens, don't gnash your teeth; the varnish underneath the skin should be just fine. Before you use it though, be sure to do two things: First, strain the varnish through one of those paper funnels with a mesh bottom (available at paint stores), some doubled-up cheesecloth or old pantyhose. This will get rid of any small bits of dried varnish that are floating around. Second, try the varnish on a piece of scrap to make sure it dries OK. If you have any doubt, toss the old stuff out and buy new. It's just not worth the risk.

Avoid the 'skin' on the varnish in the can by storing you opened cans upside down.  Don't know why this works, but I've seen this tip before and used it myself.

I have heared of putting ceran wrap on top of the paint before closing the can.

I think the idea is to avoid air to get to the finish?
