Fabric/Vinyl PAINT/DYE for seat/headliner recommendations

I've had good luck with SEM vinyl spray products but have never used them on cloth. I've also used some from Herbs parts, http://www.herbsparts.com/products.asp?cat=823 It's there own brand that I don't who there supplier might be but it's also good stuff. They have a color chart on the website too.
Good luck.....
