Aurora Alumetron Clear Polymer Coating for Aluminum - Gallon

Used it on a new triple toon pontoon boat. Used about 1/3 of it to seal the pontoons, or at least the amount I was able to access while it was on the trailer.Took about 2-3 hours to apply. The treated aluminum seems to be smoother. Looks like it filled in the very small pores of the metal, not allowing dirt to stick? Time will tell.
