A METHOD OF PROVIDING A PAINT COAT (7) OF AN ORGANIC POLYMERIC PAINT COMPOSITION ON A SURFACE OF A MOVING SUBSTRATE (4) COMPRISES ESTABLISHING A QUANTITY (6) OF THE PAINT COMPOSITION, IN A HIGH SOLIDS FORM AT A TEMPERATURE SUCH THAT IT IS SPREADABLE, IN A HIP DEFINED BY THE SUBSTRATE SURFACE AND A SMOOTHING ROLL (3) TO ENABLE PAINT FROM THE ESTABLISHED QUANTITY (6) TO PASS THROUGH THE NIP AS A PAINT LAYER ON THE SUBSTRATE SURFACE, WHEREIN THE SMOOTHING ROD (3) HAS A SURFACE ROUGHNESS COEFFICIENT (Ra) OF NO MORE THAN 1.51 AND WHEREIN THE MAXIMUM SURFACE SPEED OF THE SMOOTHING ROLL (3) EXPRESSED AS A PERCENTAGE OF THE SUBSTRATE SPEED BEARS A LINEAR RELATIONSHIP TO THE SUBSTRATE SPEED SUCH THAT THE SURFACE SPEED OF THE SMOOTHING ROLL (3) IS NO MORE THAN 1.2 PERCENT OF THE SUBSTRATE SPEED AT AN EXEMPLARY LOW SUBSTRATE SPEED OF 15 METERS PER MINUTE AND NO MORE THAN 12 PERCENT OF THE SUBSTRATE SPEED AT AN EXEMPLARY SUBSTRATE SPEED OF 150 METERS PER MINUTE.(FIGURE 1)
