This is a great replacement for gloss medium with very few differences. First, do realize it is extremely glossy. If you don't want that, I would look at their new matte medium. It is also possible you could mix the two to get your desired sheen. One reviewer noted that it stays sticky even after 24 hours. It is VERY sticky when wet and does remain a bit "sticky" after it dries. I did find that it becomes less so as time goes on. I like to use it to bring a rich gloss to the paint film and to seal layers that I have either watered down too much or use a dry medium like pastel. I have also found that it is useful for making your own paint. Until they come up with a warm yellow, I have gotten an diarylide yellow aqueous dispersion from another company to easily mix with it. Powdered pigments are generally hydrophobic and thus it takes more effort to mull it into the medium. But the dispersions come pre-wetted so to speak. It has helped to round out my color selection. I find the jar too difficult for my hands to open after use, so I decant it into old vitamin bottles. But using it from squeeze bottles has been a game changer. Looking forward to trying the new matte version! I'll be posting my reviews on a lot of their products on my Youtube channel soon. https://www.youtube.com/@ArtBreathPaintAir
