Loss of Gloss


  •   Topcoat applied in heavy, wet coats.
  •   Inadequate flash time between coats.
  •   Insufficient film thickness of topcoat color or clearcoat.
  •   Insufficient drying/curling of undercoats before applying topcoats.
  •   Using a poor grade and/or too fast evaporating thinner/reducer for spray conditions.
  •   Improper cleaning of the substrate.
  •   Insufficient air movement during and after application.
  •   Spraying over a deteriorated or solvent sensitive substrate finish without proper priming or sealing procedures.
  •   Natural weathering of the finish.


  • Allow finish to cure thoroughly, compound or polish to restore gloss or sand and refinish.


  •   Apply the topcoat according to product label directions using the recommended gun set-up and air pressure.
  •   Allow all coatings sufficient flash between coats.
  •   Apply sufficient number of coats to achieve recommended proper film thickness. Check with film thickness gauge if possible.
  •   Allow undercoats to thoroughly dry/cure before topcoating.
  •   Select recommended thinner/reducer based on temperature, humidity, air movement, and size of repair.
  •   Clean substrate thoroughly before and after sanding.
  •   For maximum holdout, use a premium two component undercoat system.
  •   Properly wash and care for the finish on a regular basis.
  •   Using premium topcoat color or clearcoat system will provide maximum gloss and durability.

For air dry situations:

  •   allow exhaust fan to run 40 minutes or longer after spraying;
  •   open booth doors after finish is dust free; and
  •   maintain a shop temperature of 60 degrees fahrenheit or above, especially when drying overnight.
