...believe what you read on labels?
 

Excuse me, but why not? Windsor Newton has been around a long time and has a very good reputation. I've been using Liquin for years and have NEVER had a problem with it. I understand that some people don't like the way it handles, but I can paint rather well with it. Yellowing and cracking is just not a problem.

Dear Karin,

I was merely recommending superior products to a colleague.
In whatever claims, however fanciful, that may be made about this stuff no one recommends that a hard oil varnish should be employed where a soft resin in a sovent is appropriate. Both will eventually darken. The later can be removed with less chance of spoiling the painting.

Dear Karin,

I just looked at my bottle of Liquin. The label reads: "Good resistance to yellowing."

This bottle was priced at $6.25 for 75ml. Good copal or amber varnish will run from about $40.00 to about $700.00 depending from whom one purchaces them for the same volume. Speaks volumes?

Alkyd resins, undiluted with additional oil or solvent, are priced at $4.00 for 75 ml at Kremer. Their alkyd mediums are $4.00.
