Maintenance
Repairing Surface Damage to Powder-Coated Towers
Scratch Repair
1.
Carefully sand the damaged area to clean and score the base metal, taking care to minimize any
additional damage to the surrounding powder coating.
2.
Wipe the sanded area with a cleaning solvent, such as DuPont “PrepSol.” Allow the area to dry. This
type of product is available at auto parts stores. Denatured alcohol can also be used.
3.
Prepare the bare metal surface for painting by treating it with a phosphoric acid solution intended for
this purpose. Allow the area to dry.
4.
Using a cotton swab or small brush, paint the prepared surface with an automotive enamel or oil base
polyurethane enamel such as Red Devil
®
or Rustoleum
®
. DO NOT USE Krylon-type paints.
Carefully blend the repair enamel into the powder coating at the edges.

EXACT color matches may not be attainable.
Decal Repair
1.
Use a sharp instrument, such as a razor blade, to loosen and lift a corner edge of the damaged decal.
2.
Carefully peel back and remove the loosened decal.
3.
Wipe the area clean with denatured alcohol. Allow the area to dry.
4.
Prior to attaching a new decal, dampen the target area with a fine mist of water (fine spray from a
plant misting bottle is ideal).
5.
Peel the backing from the replacement decal, leaving the decal’s front cover material attached, and
carefully align it with the target area.
6.
With the cover material still attached, press the replacement decal in place, then squeegee any water
from under the new decal starting at the center and working toward the edges.
7.
Peel off the front cover material, being careful not to tear or lift the decal. If the decal lifts as the
cover material is being removed, push down on the uncovered decal, and squeegee as necessary to
remove any large air bubbles; small air bubbles will disappear as the decal dries.
