Like John said above, these buffer pads are available from other online places, treasure cove just supply their own mix of compound. I have had great success with a kit (of pads only) I got from pinrestore and then made up a bottle of 1/3 novus 3 and 2/3 novus 2 and used that to start, then novus 2 etc. But if you are concerned etc then I guess the treasure cove kit with their own mix is tried and tested.
p.s I have only ever used it on diamondplate fields
Edit: Changed the quantities of Novus, got my mixed bottle out to use and noticed I had posted the incorrect quantities (Also noticed today that pinrestore will no longer send liquids overseas i.e polishing liquid, flitz etc
