We know of a kit but we don't recommend it. All the information you need is available here on the forums for you to build your own kit, preventing you being over charged for chemicals which the company that produce the kit repackage and name in an attempt to give you the impression that they are their own chemicals which they have developed.
Get yourself a copy of Hoke's book, available as a free download from the book section or many members signature lines, read it until it makes sense to you,and read the many posts on the forum dealing with the specific refining processes you are interested in and then if you still don't fully understand ask questions, but, always try to answer your own questions first using the search function, top right of the page.
