The SRP kit was great in its time, (this is just the Novus kit rebranded) it is quite expensive and requires a depth of knowledge to work with. We have loads of them just gathering dust now if you want one. We tend to use the Scratch Polish kit from Scratch Polish UK
www.scratchglass.com its about £500 with most of the consumables. The guy who runs it is really knowledgeable and can provide ongoing support. We get all our stuff from them now. Hope that helps.
