Treated or Untreated UltraLeather
 

So I've read a lot on people buying and using Ultra Leather for there DIY interiors and I was wondering if they are getting it treated with Flame Retardant from Tapis industries or just off the shelf untreated? I talked to a salesguy at Ultra Fabrics in there Aviation department and he said the ultra leather by itself doesn't meet Far28.853, but they partner with Tapis who treats the material to meet the reg and then sells to the public. Just curious if others are going this route, or being we don't need burn tests they just go with the base stuff?
