For a while now I have been using Optimum polishes and compounds. But reading the labels of OHC and OC leave me questioning something...I thought that OHC is more aggressive than OC. Isn`t this true? But, reading the labels of both products, OC directions say that it can remove a maximum of 1200 grit scratches. Reading the label of OHC states that it can remove 1500 grit scratches. So the big question here is, which one is more aggressive? To be honest, using both seem to offer similar results.
