Gloves are a good idea. I don't wear them myself often but then I have leather skin I've gotten better about wearing them and not trying to get so much paint on me vs the painting
There are water based oils now and I've seen some pretty impressive work done with them.
One thing to be aware of is "paint thinner" is not always "paint thinner".. here in SolCal its virtually impossible to buy normal plain old Odorless Mineral Spirits due to govt interference. What they sell as OMS can be a wild mix of really obnoxious chemicals that are worse healthewise then the "bad" OMS. And if it's sold as "Paint Thinner", thats even worse. What I found in some research in MSDS ( material safety data sheets) is that Kingsford BBQ starter fluid is really OMS in disguise and legal to buy. There is some available at outrageous prices in art stores but it's not always pure OMS.
OMS will evaporate if you leave the lid off but like it's been said, use it, cover it and then the solids settle to th bottom. I just swapped cans and my base of OMS is now about 3 months old with some new added to top it off.
And ( borderline heresy ) you can follow someone else like MazArt Studio who uses wet on wet like bob but in much smaller quanities of paint. I mean MUCH smaller quantities She rarely cleans her brush and prefers to wipe it off on paper towels.
