I have a client who is interested in putting
(spraying) a protective coating on upholstery fabric
(reproduction not original) on several chairs as she
is very concerned that even the slightest soiling will
be very visible and ruin the look of the upholstery. 
Does anyone have any experience with protective fabric
coatings or any other suggestions?  Any comments would
be welcome.
Thanks,
