Cause:

  1. Improper surface cleaning or preparation.
  2. Wrong gun adjustment or technique; paint application is too wet.
  3. Thick paint application
  4. Wrong thinner or reducer; solvent is trapped by subsequent topcoats or Solvent pop breaks from paint layer

  5. Allow sufficient flash and dry time.
