One category are buffing pads made from wool.  There are also blended pads; that is pads that have a mix of wool and synthetic materials.  Depending on the purpose, wool can be spun into various yarns, some are twisted, some are not.  For example, if a customer needs a buffing pad that is aggressive, we can offer him/her a buffing pad that is 100% twisted wool.  Twisted wool is considered aggressive in terms of cutting ability.  On the other hand, if a customer wants a buffing pad for final finishing or non-aggressive polishing, we can provide yarns that are non-twisted or made with a mixture of synthetic materials.  Buffing pads can be made for a specific purpose or multipurpose.  Our approach is to simplify the buffing system and we also suggest working with various car care chemicals, such as compounding, polishing and finishing products.  There is an obvious relationship between buffing pads and polishing compounds.  It takes time to learn how these products work with each other.  One thing is certain: wool is becoming more popular as paints are required to contain more solids and fewer solvents.   Wool is simply the faster medium when compared to foam pads, it cuts quicker.  Foam pads play a major role in buffing as well.  Generally, foam is considered most useful when finishing.   The rule of thumb is to start with a wool buffing pad and finish with a foam pad.
