You probably wouldn't find Rustolium in a automotive body shop either Stu. My point was that it is rumored that you can add the hardener to Rustolium enamel and that simply isn't true in all cases. Remember, this is an experiment!
Now you may be right about the mineral spirits, that same thing crossed my mind also. If the 2612 is catalizing the mineral spirits that may be what is happening. Rustolium can be thinned with many different thinners, Acetone is also called out by the manufacturer and I'm planning on trying a batch thinned with that and adding the 2612 to see how it reacts. However, this time I will spray the cardboard box first.
But the bottom line here is that this is an oil base enamel and not Acrylic Enamel which the hardener is formulated for. So there may be some bad information getting spread around about the use of 2612 Wet Look Hardener.
