Topic: Seat material?

[Boy named Suzi]

Heh project folk,
 What is the best, if not proper seat material for a 78 Honda. I am not interested in 'authentic', just good looking and servicable.
 
 I am a furniture maker by trade and do some upholstery as such. My suppliers will not offer a 'weather-proof' material in black. Does a bike seat need to be 'weather or water proof'? Mine bike lives outside and gets covered often, I beleive the issue is rot setting in if it does not dry out.

I am not into upholstery but have sat on bike seats for more years/miles than most.  You don't really want to sit down on a seat that has let the foam become a soaked sponge.  It also rusts steel seat pans.  Factory seat covers are just good quality heavy vinyl upholstry material.  The vinyl is waterproof.  Stitching is just poking a bunch of holes in your seat cover.  Stitching is not waterproof, so if you want a water proof seat then don't stitch on the upper surfaces.

Thanks, when I do recover it I will be religious in putting a cover over the bike. Looked into Marine seat material and it is water proof  to the extent that it still has to be sewn or formed. Forming is prefferable as it does not puncture the material.

Also ordered the 'outdoor' thread, nylon for strength and cotton cover to swell in the wet and plug the hole...in a thread!
