“I recently finished a steel exterior deck railing and plan on coating it with a polyester powder.�Will a clear top coat enhance the durability of the finish and protection of the railing?�Is a clear coat standard for this type of application? I like the appearance of the matte look but if a clear coat will better protect and extend the life of the finish I will consider it.”

“Don’t bother with the clear powder. They are only used to enhance the gloss of the underlying surface and will not improve weatherability. Since gloss is one of the first qualities of finish to degrade as the coating ages, use a good TGIC or acrylic matte black finish.”
