Can I mix two versions of the same resin?

This was addressed by FL in an earlier post since a lot of guys where running into the same issue.

New/Old Resin Compatibility

Hello. Yes, you can use Grey V4 mixed with remains of Grey V3. Explained: I had the following situation. It is known, that Formlabs recommend to use standard resin tank for 2 liters of resin. As soon as i have finished first liter on Grey V3, it was impossible to buy V3 due to it’s upgrade to V4. I asked Formlabs support if i can mix V3 and V4, and they confirmed that. Pour remains of V3 somewhere to left resin tank out of it as much as you can. Do not use any cleaners of something like that…
