Ordered some SPI-2010 black base coat. There is a warning label on the lid that reads "DO NOT USE UNDER FLATTENED CLEAR UNLESS YOU TEST FIRST!!!".
Why the warning? What is the potential problem? Or is it the warning just for non SPI clears? I don't want to call you on the weekend unless I have to.
I have done this quite a few times with the Euro clear, but not with this base.
