Typically, we offer up to 3 stages of paint correction on a vehicle. The first stage is the cutting stage. Here, we use an aggressive cutting pad, typically made of microfiber or wool, along with a cutting compound liquid, to remove heavy defects and swirls from the paint. The next step is polishing. This is done typically using a foam polishing pad, and a liquid polish. This does 2 things, remove more minor swirl marks and scratches, and leave the surface extremely clear and glossy in preparation for coating. The 3rd and final step, which is less common, is ultra fine polishing. This is done with a very very mild polishing pad, and heavy polishing liquid. This is done to further exchange the gloss and overall appearance of the painted surface prior to coating.
