THE BLEND COAT SIGNIFICANTLY REDUCES THE POSSIBILITY OF SCALING AT THE PERIMETER OF THE REPAIR UPON COMPOUNDING AND FINAL POLISHING

* ALLOW 15-30 MINUTES FOR THE LAST COLOR COAT TO FLASH. THEN APPLY PASSES OF BLEND COAT MATERIAL AT 15-20 LBS. GUN PRESSURE TO MELT THE OVERSPRAY, FOLLOWED BY TWO COATS OVER THE ENTIRE REPAIR, STAYING WITHIN THE SEALED AREA.

* ALLOW THE REPAIR TO DRY THOROUGHLY. RUB AND POLISH BEYOND THE REPAIR AREA.
