Varnish blister?

Here's one I haven't experienced before: in two places on the exterior woodwork (one on the toe rail and one on the inside of the cockpit coaming) there have appeared 1 1/2" blisters. The varnish swells up with air and looks just like a blister from poor fitting shoes. It happens on warm sunny afternoons. I'm assuming it is due to moisture under the varnish, but this is a first-time occurrence in over five years of ownership of this boat in the same environment, with the same Epiphanes varnish applied every 4-6 months.
Has anyone seen this?

At least you know that your varnish is a good vapor barrier!

Those blisters are likely caused by painting in direct sunlight on a hot day. The varnish skins over and dries trapping wet varnish underneath.

Yes

Yes, I have. Unfortunately it's time to get out the old heat gun and remove the old varnish. It has lost it's hold on the wood and will only get worse with time.

Thanks for the ideas...
It is almost time for the spring re-coat, it will have a bit of extra attention in a few areas. I think you are correct Dwayne; the blisters look like its all the way detached from the wood. Hopefully a complete removal of that area plus an inch or so will suffice. If not, well there's another six week project to add to the list!

This has happened to me also. I'll bet that when the first coat was laid it was a very warm day and perspiration dripped of off your nose onto bare wood. If a drop of moisture lands on already laid dry varnish and you hit it with the brush (especially foam) it will turn into a bunch of tiny droplets and very tiny bubbles. On dry wood one must be very careful and use a tac cloth or non -lint tee-shirt material.
