Osmosis (Blisters), Stress (Spider) Cracks

Osmosis and stress cracks are both serious issues, especially if you are experiencing either one of these issues on the hull of your watercraft. If left untreated, osmosis will slowly add more moisture into your hull which will ultimately protrude into the core of your boat. Both are visually unappealing, but more importantly both are significantly damaging to the long-term health and value of your Boat or PWC.
