Recently finished designing and printing a few figures out of ABS. During the vapour smoothing process, I went out to get a few paints (very small prints so didn’t want to go for full cans of spray paint). Unfortunately, I hadn’t realised they were oil paints (acrylic based). Wondering if they are still suitable for ABS with a standard acrylic primer or of I need to do anything special?

It will work fine and cause no harm to the ABS.
