I'm just looking ahead to when I get to this step in the process as I like to look out ahead for sales and get things before I need them. So I am finding the array of products available as overwhelming in the abrasives dept as they are in the spraying products. Is there a sticky or post (I haven't found one yet) dedicated to what people have found works well? I want to avoid buying inferior products that will waste my time, money, or worse the finished product.
