Blade Sealing

Water penetrates the blade through micro-cracks in the blade skin. After the water is removed and repairs are made to the damaged areas, the blades are sealed using the AvTask Blade Sealing Table. The table’s unique design heats the upper surface and chills the lower surface to improve sealant penetration. Sealing the blade will eliminate/mitigate future water contamination. see more...
