Les oil paint should dry a few days. But there are some ways to speed up the process
But I try as much as possible to use these colors if it is not dried until the end. If I decide sprayed of the varnish is just wait a few hours to paint
and sprayed with a thin layer gently several times with an airbrush.
I use this 3 types of coatings, such as in the picture. Depending on what effect I want to get. The first two Talens allow us to obtain greater transparency of colors and can dry a little longer. Testors paint will give us a larger mat.
If the varnish is dry you can apply the fix. Applying then I paint diluted white spirit, turpentine and linseed oil even better.
Another bunch of photos ... I approach the end of a painting. Now gonna put a bust for a day to dry and then I put the fixes.
