From ramana murty of International Paint on June 13, 2013:
Consult the manufacturer of the paint, and if the over-thickness is within the limits and there is no sign of defects, then leave it without further damage to the applied coating. If the paint rep  recommends removing it, then go for sweep blast with fine copper slag (0.2 to 0.5mm abrasive size) and reapply full coat of top coat.

From Ahmed Abd Ellatif of ENPC on June 10, 2013:
Completely remove the topcoat layer by sweep blast and apply another topcoat.

From Yan David of DNVGL on May 22, 2011:
If sanding is used,workers should pay attention to the sanding job, because sandpaper marks are difficult to cover with a topcoat paint.The look of the topcoat is important.

From remko tas of Futuro SRL on May 10, 2011:
     If the overthickness is present at spots only, sand it down to the coat below and repaint the area. In case the whole object has a topcoat with overthickness, first analyze if this has impaired its performance (check on paint cracking and ultimately do an adhesion test) before deciding if it is wortwhile to remove the topcoat. If so, you may consider more eficient ways to remove it such as doing an abrasive blast and starting the whole paint scheme again.

From Muhammad Iqbal of CV. Kharisma Selatan on May 9, 2011:
Sand it down to a little bit to below the specified thickness and apply a thin coat for cosmetic purposes.
