Leather Prep Solvent

[Mr_B]

Am half way through doing a colour change to a set of seats and run out of leather prep solvent. Will order this and some other bits from the kit supplier, but does anyone know if I can get this locally ( B&Q , DIY stores paint places ) and what the solvent is exactly ?
I'm guessing it's a common solvent you can buy by the liter a lot cheaper than the small bottles sold by kit suppliers.

Isopropyl alcahol [ipa] is what your after it's not to hard to find via google or your local chemist.

Sorry, should have said this is not IPA. Its a solvent that will remove the colouring dye like paint stripper does to car body work. IPA is uses after the solvent as a final wipe-down before applying the colour dye.
