I have a problem with sporadic paint bubbling on the teak transom clinker type paneling applied over the fiberglass.Like GBs, the teak is varnished by the builders. Some work shy PO painted it.
There were sporadic bubbles when I bought it 7 years ago. About 5 years ago I had it repainted, it was thoroughly sanded and prepared, though the first finish coat went "flat" due to ? a moist overnight. It was resanded, and repainted, 2 pack. The boat was in a shed for osmosis work etc, the transom faced the opening of the shed. It is possible the transom got light rain spray, but for that to be the cause, it had to get wet both times it was painted, which requires an unhappy coincidence.
I wanted to return to varnish, advice was that once painted, it is near impossible to get all the paint off, so new paint. The repaint bubbled in short time. The bubbles don`t change or burst, the only open one was cut open for exploration, it seemed to hold water.
I don`t rule out trying to get the paint off and varnishing again. Alternatively repainting, maybe with a durable plastic domestic outdoor paint to allow moisture through(relying on a house reno project experience where the specialist builder engaged to fix damp issues said it was ok to paint the fresh set render with plastic paint but NOT with an oil based paint,worked out fine).
I would appreciate similar experiences,thoughts on cause,and remedies. Especially on removing the paint and going back to varnish.
