I was getting tiny fish eyes that would start to pop up shortly after application. I thought it was a spray thing but to my surprise it also happened when brushing. I got a can of Advance and everything went on fine. I ended up getting refunded 10 gallons through my BM rep. He said there had been a similar problem with a local millwork supplier that was using Scuff-X.
I should say though, the cans were actually from three different batches, so to say it's a bad batch may not be entirely accurate. More so I got some bad cans, or maybe there was multiple bad batches. This was in November so I wondered if maybe the product had gotten too cold somewhere in shipment.
