I used it for finishing on PLA printed figures, which were painted with the corresponding Amsterdam acrylics. Very good effect, as you can see it is not completely matte, it is closer to the finish of the paint itself. Absolutely suitable for the job I wanted it for. It smells a lot, so it definitely needs to be used in a ventilated area, but in a relatively short time it solidifies and loses that smell, so drying can be completed indoors. It needs at least 24 hours for complete solidification but after that it is unbreakable. It has the right consistency for 3D objects, as it is thick enough not to run much and spreads very easily. I also tested it on Angelus skin colors out of curiosity but they do not react well together at all.

Overall, absolutely satisfied!

It does the job, personally because I work with mixed media I used it over acrylic, marker ink, and watercolor paint and there was no "leakage" between the colors. I remove 2 stars because the smell of it lasts for days, more than spray varnish
