Review on 150ml Gamblin Solvent-Free Gel Medium: Optimize Your Search! by Angela Rodriguez

This is the only oil paint thinner that is safe and legal. The consistency is similar to varnish and, sorry for the term, looks like "snot". I like to take paint with me when I travel, so that's not a problem. But I keep a little on my palette to mix colors instead of average. I especially like painting with a palette knife to add volume to my mixes while still keeping the paint nice and thick. It doesn't add color and stays in place like most colors. It dries up a little glossy so that's a matter of taste, but I like it. I'm using it more and more over time, so that's a good sign. The drying time does not differ from the drying time of a conventional medium.
