3M's unique paint rectification processes and products can help you achieve the desired result for your customers.
Whether you have to remove surface defects or just want to achieve the perfect finish - our easy to follow guide to our compounding processes can help you achieve great results in just a few steps.
For freshly refinished panels:
Just two 3M™ Trizact™ sanding steps are required for an excellent result: grades 3000 and 8000. Followed up with 3M™ Perfect-It™ 1-Step Finishing Material.
For hard fully cured, or OEM clear coats:
Use the 3M™ Perfect-It™ Colour Coded Polishing System to obtain a high gloss, defect free surface. Our colour coded products are designed to compliment each other and the colour coding assures that you use the correct compound with it's corresponding foam pad for best results.
The combined circular and oscillating motion of the 3M™ Perfect-It™ Random Orbital Polisher eliminates the dreaded swirl marks common with traditional rotary tools. Paired with our specially-designed pads, compound and polish, you can expect a consistent high-quality finish on any job big or small.
To achieve the perfect finish for your customers, the key is to use the correct application process for your clear coats - stick to your paint manufacturers recommendations!
State-of-the-art modern clear coats are very sensitive to drying conditions, which can determine the difficulty of your finishing process and the overall quality of your result.
The bake time paint manufacturers' recommend usually refers to time in the oven at "object temperature".
The key is to identify how much additional time is needed to heat the object to temperature and add this to the baking time.

The longer the open time of the hardener (type: slow), the longer the cure time will be to achieve a fully cured coating.
The thicker the overall coating, the longer the cure time will be to achieve a fully cured coating. State of the art High Solid Clearcoats achieve higher thickness layers per application.
Different paints and coatings can perform differently – paint type, booth temperature, application system, curing times and many other factors can affect how a coating will react to an abrasive and polishing system. Please choose the paint finishing system that suits your needs and situation.
