All of these reports about problems with the foam turning into liquid are very interesting. It certainly hasn't been my experience. Have you contacted the manufacturer about it? I wonder if it was just a bad lot...
I used my first foam can and I had no problem i.e. it didn't trun into liquid. I started the second can couple of days back and when I used it first time the foam was turning into liquid but I stated shaking the can before application and it seems working for me (i.e. it's not turning into liquid) any of u guys tried shaking the can before using.
I find that the foam is more "liquidy" when it's warm in my room. I never had it turn to liquid straight from the can though. Maybe storing it in a cooler dryer place will help?
