Poorboy's World Pro Polish 2 is a heavier duty, more abrasive version of our original Professional Polish. When we had customers who were dealing with heavy metal polishing and said we need Professional Polish with a bit more cut, we listened. Some early testers of the product called it their "Secret Goo" Pro Polish 2 is a task specific improvement of our Professional Polish, Pro Polish 2 contains abrasives and blasts through heavily contaminated metals. When we tried Pro Polish 2 on paint we were surprised to find that it worked great as an initial cut on a severely neglected finish. So if you are looking for something with a bit heavier cut than our Professional Polish you have found your product.
