Repairs range from the complex to the simple. One end of the spectrum consists of sealing the boat in an airtight bag and using commercial dehumidifiers to suck out all moisture in the hull followed by completely cutting out the blister and repairing as one would repair a hole in the hull. Many people will let a hull dry out for weeks after lancing and opening a blister. On the other end of the spectrum, some people will do little more than lance a blister and almost immediately putty over it. Prevention currently consists of applying several thin barrier coats of epoxy to the hull.
Epoxies are less porous than the polyester resins used in production fiberglass boats.
The system is quick and easy and allows users to also include more extensive repair procedures should they deem ti necessary. We believe our system offers a suitable solution to most blister situations. Ultimately however, it is the boat owner that must decide how extensively to repair blister damage. As the blisters are generally filled with liquid expect a mushy mass of fiberglass dust to fill the area. Thoroughly flush the blisters with water either from a water-blaster unit or garden hose.
