That's an interesting story!  Sometime mid-year, last year the clear coat started flaking off of the driver's side of our 1990 Contessa.  We thought it occurred because the coach is stored in a North-to-South direction and the sunlight (UV) had finally got to it.
We appreciate your 'quick-fix' using rattle can clear coat; great idea!  However, do we continue to 'fix' as other areas begin to peel or should we bite the bullet and get the whole coach re-coated professionally?  What did you do for recurring problems - or did it stop?
