Medium that I use for Oil Painting (answer to a question I received)
Over the years I have used different mediums, but the one that I like the best now is the following recipe:
1 part Damvar varnish
2 parts stand oil (sometimes I use linseed oil)
3 parts odorless mineral spirits (gamsol)
I use a small amount with the paint in the later stages of the painting to help it dry faster. In the first stage of the painting I use gamsol only.
Note: Sometime I don't use medium at all. Fresh paint can be just the right consistency without medium.
