Well it's been a year since I purchased the Blue Heron and she came with some blisters. The bottom paint probably has never been scraped or sanded so when we pulled I decided to have the bottom soda blasted and etched.
Here are some pics.
Took one entire day to get one side if the hull done. Some small Knicks in the glass most of the blisters appeared to be paint in paint. Moisture readings are next.
Decided after much research to blast and barrier cost and repaint. All appears to be cosmetic.
