Motorcycle Leather

Best product to seal a new leather motorcycle seat?
I’m making a new motorcycle seat cover out of ostrich leather. (It’s actually pig leather stamped to look like ostrich) What is the best product to seal it with?
I don’t think it’s possible to “seal” it entirely, although leather obviously has natural sealant properties – which you’re no doubt aware of – but it will always “breath” a bit and take on some moisture as it wears.
Your best bet is to speak with someone at a furniture store that specialise in leather sofas and chairs, or a saddelry. They’ll have products (waxes, polishes, semi-sealants) that won’t rub and stain your trousers (as opposed to a lot of the stuff you can get for leather boots and shoes).
I’ve often used ‘Dubbin’ (a waxy restorer) on leather boots and saddles – it makes them more supple and provides some protection from rain. And my school coach used to always get us to use Dubbin on our leather boots and footballs. There’s also a few silicon-based sprays and products (e.g.: Scotch-Guard) which may be appropriate, and a range of saddle soaps and polishes that should be perfect for what you’re after.
