In the Show Polish aluminum kit you will find only soft buffs and light compounds. What does this all mean? This means that if your truck or the item you are polishing is in good shape you can take it to that next level. Furthermore, if it is in rough shape, you will not get great results. Please consult my YouTube channel by clicking here to find out what the difference is between the 2 types of compounds. But as we all know, polishing is all about minimizing or eliminating hash marks. The less hashmarks the better and shinier. By starting your cut stage with a softer buff and softer cutting compound you can finish with much softer and better finishing results.
