Pinholes in polyester affecting the final coat
OriginPolyester used was not dried properly.
Putty was not isolated at all or not isolated properly with 2K filling primer.
Pores were not sanded deeply down.
AvoidanceAllow each coating during the preparation of substrate to dry thoroughly.
Make sure you sand down all pores.
Use fine fillers to seal any pores remaining from the polyester.
During polyester application make sure the hardener is mixed properly and try to avoid any air bubbles.
Proper application of polyester prevents the formation of pores.
How to fix the problemSand the damaged area down to the polyester.
Check the substrate for pinholes.
