One of my favorite things to do other than painting is varnishing. Varnishing a painting
brings it to life, makes colours sparkle like I meant them to be. We all know some dark colours drop (dull) when they dry. A
light thin coat of GAMVAR picture varnish evens things out - in my book absolutely necessary
before releasing or showing a finished work of art! What is amazing about this formula is how even the finish is with very little material application. I found less works better than more. More can stay a bit tacky longer than a thin application....regardless, the finish never looks starved (sinking in or highs and lows).
GAMVAR - picture varnish
Conservators and museums dealing with old nasty yellowed varnish on a
daily basis engaged technical help from the Gamblin people.
Gamblin was able to produce a workable, removable water-white top coat formula they could use. R&D in this case also benefited the artists because this stuff is also available over the counter and it works!! A quality, removable top coat that can be
applied within a week or two when the surface is dry to the touch.
Impasto obviously takes a bit longer and should be firm. Generally for me that's about 2 or 3 weeks.
Mineral sprits will remove this particular varnish top coat rather
quickly. Oh! And the best part its also odorless!

with an informative video about GAMVAR. I just looked at it and learned a
bit more - cold wax is apparently also used as a top coat and can be
mixed with this material to reduce shine.
