Vallejo - Retarder Medium (18ml)

The texture of my paint stays exactly the same after mixing a few drops in, which is huge for me since I hate thinning it out. Now I can blend wet-on-wet for a solid extra ten minutes without rushing, and the tube lasts a surprisingly long time for 18ml.

Adding just a few drops to my wet palette keeps the paint workable for almost an hour longer than usual. The consistency stays exactly the same, which is perfect for blending on the model. This little bottle solves my biggest frustration with acrylics drying too fast.
