All of the gels that we carry dry glossy and clear (Nova Gel #207, Super Nova #209 Gel, Flex Gel #213). The only exception is Matte Gel #208 which dries matte/waxy (as the name suggests).
The main difference between Nova Gel and Super Nova Gel is the consistency. Super Gel dries extra stiff but to the naked eye they look exactly the same. If you're interested in our gels and have never used them before we suggest starting with Nova Gel #207.
Since our paints have a creamy fluid consistency, our gels can thicken the paint to create impasto.
