In the spray process, paint mists drop on the paint finish and make the paint finish rough, full of small particles and loss of gloss.
Common Cause
Incorrect spray method: Spray gun too far away from the surface, not vertical to the surface, spray speed too fast, or air pressure too high.
Incorrect viscosity; thinner too fast.
Too near to the surface and easily affected by the paint mist.
Poor ventilation of the spray booth.
No covering of the part unnecessary for application.
Dirty or damaged spray gun.
 Repair
(1) Primer: Allow it dry, then sand.
(2) Topcoat: Fine sand the last layer of dry spray, then polish.
(3) Single layer silver basecoat: Sand and respray.
