### ⭐⭐⭐⭐⭐ Easy to use.
*by L***C on May 17, 2025*

Easy to use. Just a couple of drops and your paint is smoothGreat value, works well

### ⭐⭐⭐⭐⭐ This stuff works great!!
*by L***J on December 17, 2023*

I had started painting during Covid out of boredom, hoping that my mom's talent had been passed on down to me. When things started to get back to "normal" (as if they ever really will, lol), the unfinished painting sat on the easel for over 2 years. Now I am scheduled for rotator cuff and bicep surgery on my dominant arm and I am bound and determined to finish the painting before surgery. Except the paints had become unworkable. Not really expecting it to work, I bought this thinner and, lo and behold, even the most gunky, dried up colors are workable again!! I was so amazed and grateful! I would buy again, although it will be many months until I can paint again after surgery.

### ⭐⭐⭐⭐⭐ Great product
