Valiant Blister History?

Any vessel with extensive large blisters or overlapping small blisters, ie, they are in different laminate layers, should be considered suspect in regards to structural strenght. Peeling, glassing, fairing, and sealing of surface blisters is a relatively mindless proceedure, but when they go deeper into the structural laminates, layup of the new glass must be in accordance with the designers specifications as to type of glass and direction in which it is applied. Always remember that secondary bonding of fiberglass layers is weaker than original, continues layups. That is why an epoxy resin should be used. By the time you grind, dry, fill and fair, seal, and bottom paint a forty foot boat with extensive blistering by yourself, well, I hope you started when you were young.
