I applied polyurethane to some molding today in my garage and I noticed a short time later that rather large bubbles had formed on the surface. There were NO bubbles when I was done and this was something that happened later.

Has anyone else ever seen anything like this before? Is it because of the heat (it wasn't real humid today)? How can it be prevented?

This was caused from the heat and im really suprised that no bubbles were there when you were done.
What is happening is the stuff is drying to fast and shrinking up causing the bubbles.Did you have the wood in the garage overnight?If so it could be the wood heated up when the garage got warm thru the day,either touch the wood and see if it feels warm before doing this or wait for a cooler day and by all means avoid doing it in direct sunlight and don't set in sun to dry.
