If you read a post I made in the paint section a few months back I had the exact same issue. It had rained cats and dogs that day, and the paint I had applied didn't have enough dry time. I noticed the bubbles like you are describing. I took the liberty of scraping the paint off while it was wet, however once it started to dry it became impossible to strip again. Hardened right back up. I came to the conclusion that the Behr paints need a full month of dry warm weather to fully cure and be water proof. In my case the paint had been applied about 2 weeks prior to the raining. I eventually decided to strip the truck (about HALF the truck) of the house paints I had applied and as of just a week ago I barely started repainting again with the proper enamel this time from Aervoe. I've been working since that rainy day trying to remove the behr, it's tough stuff dude. Tough stuff. But, I only have a little left to go then I can finish painting with the enamel. I kept the Behr on the troop seats, though. No way I am stripping every piece of wood again.
I tried scraping, wire wheeling, paint stripper, denatured alcohol, boiling water, a heat gun, brake fluid, diesel, gasoline, etc. None of them removed the Behr paint that easily. I eventually fell on using 100 grit good quality sand paper to take the Behr off. By far, sanding works the fastest. And it's cheaper than using 100 gallons of stripper.
