I have a question about using isopropyl alcohol as a substitute for OMS. In one of his tutorials, Mark talks about using alcohol to clean palettes, and I've found that it works very well. Today I gave up on a painting I'd been working on and decided to scrape the paint off so the panel could be re-used. Since the rubbing alcohol was close by, I moistened a paper towel and wiped the panel. It worked great and I was happy that I didn't have to mess with the OMS.
I wonder, since I know nothing of chemicals, if this is a good idea or should just stick to the OMS and use the alcohol for cleaning palettes.
Many thanks for information anyone might have regarding OMS vs isopropyl alcohol.
