Paul, they are all the same at the end of the day. They can come up with all the marketing blurb about dyes and pigments,etc etc but in realitynone of them are dyes they are all PAINTS and are not by law allowed to call them dyes so thats where the blurb comes in and they call then a different name like BRITT

for example.
Its similar to carpet cleaning chemicals called Micro Splitters

What is a micro splitter?
On leather ive used Buffalo for years done training with them and they are great and their product work well for the professional, ive done loads of recolouring and never had a problem.
Oh they have just bought out a great cleaning sponge and it makes light work of cleaning a really dirty suite.
Have you caused a storm. No not really. Having spent an hour reading through back pages of Judys posts I think she is the main antagonist when any thing is posted regading leather.
