I decided to test Optimum Hyper Compound against SSR 3 via the PC. I regularly use and like SSR 3 but thought it was time for a head to head test. The first two pics are before any polishing. The test vehicle is my white 97 chey pickup. Notice the heavy swirling and deep scratching. I'm going to use SSR 3 to the left of the tape and OHC to the right.
