No idea. It's a single-action airbrush that has a constant airflow, a decent airbrush is a double-action one where you also control the airflow and the mini-compressor might not be suitable to deal with that.
Just go for it, it's dirtcheap and just for being able to prime makes it worth. I've yet to use varnishes but gonna try that out soon as well. Make sure to grab some airbrush thinner and some isopropyl alcohol for cleaning stuff. It's probably gonna die on you, which is a good learning experience and you can just replace it for 4 dollars provided the compressor still works.
