Abstract
In at least one example, a composition for surface activation of an aerospace vehicle consists essentially of an organic solvent present in an amount from about 95 to about 99.5 volume percent, a transition metal alkoxide present in an amount from about 0.5 to about 5 volume percent, and a water content in an amount from about 0 to about 5 volume percent. In at least one example, a method of sealing a surface of an aerospace vehicle includes applying the composition to a surface of an aerospace vehicle. The composition applied to the surface is dried to form a transition metal oxide from the transition metal alkoxide. Excess of the transition metal oxide is removed from the surface. A sealant is applied over a remaining layer of the transition metal oxide on the surface.
