SCHOLL Concepts S3 Gold XXL is a 500 lb gorilla in the world of car polishes. Q: What kind of paint defects will it remove? A: Any that you dare show it! It's packed to the rafters with high-purity aluminium oxide diminishing abrasives, which cut ferociously to begin with, meaning that you'll correct even very severe defects in no time at all. However, these abrasives then progressively break down to form a polishing rouge that gradually refines the finish, meaning it's often possible to correct and refine harder paint types in a single step. That said, in cases where time is not pressing, following up with an ultra-fine finishing polish such as SCHOLL Concepts S30+ or SCHOLL Concepts S40 will improve the finish further.
