Paint 911. Used wrong activator.

I agree. Use MEK to get the bulk of it off. Wear a respirator and heavy gloves. MEK is nasty stuff. Because the chemicals are a mismatch it will still be tacky so use acetone to wipe the residue off. Acetone will suck out the tacky polymers and you should be able to let it dry and lightly sand for a re-coat. An incorrect chemical bond may never cure and even if it does you will see a difference in finish.

Grab a six pack and get busy.
