 Has anyone ever  used a product from 3M called "Is That Leather".  It's been
 in  my Glasair since 1991 and it still looks like its new.  Having to  climb
 into my plane all the time, stepping on it and it still looks good. It's
 also
 on the glare shield with no ill effect. That's what I'm using in my Lancair  
 IV thru out. Time tested and still going strong!  That's my 2 cents  worth.
