Condition:

    Similar to cracking, except that the lines or cracks are more parallel and range from very short up to about 18 inches.

 

Cause:

  1. Excessive film thickness.
  2.   Improper surface preparation.

Prevention:

  1. Avoid piling on topcoats. Allow sufficient flash and dry time. Do not dry by gun fanning.
  2. Thoroughly clean the substrate with PCI degreaser before sanding it. Ensure the surface is completely dry before applying undercoats and topcoats

Treatment:

Sand down the topcoat completely and repaint it with PCI alternative products listed.
