Jim - I am looking at a fabric a/c with 25 year old fabric. A recovery
will run into 5 figures. Assume we do not know the entire history of
this coating; no log entries stating "under cover from X to Y" so I
have to guess at how long we have remaining on the fabric.
Any suggestions on how that can be done? - Mike
