Ian,

My old LS-4 was partially refinished in Prestec about 5 years before I
bought it. It was clearly an Earl Scheib special (for those of you outside
the US - Earl Scheib = cheap auto refinisher of marginal quality). Within
2 years of my purchase, significant checking appeared in several areas.
Inspection with a 4x loop seemed to indicate that the crazing came from the
substrate (old gelcoat) not the outer surface. I think it just reinforces
the conventional wisdom that any areas of loose or badly crazed gelcoat need
to be removed prior to any sort of refinish.

Does anybody out their own a ship which was refinished without removing
all
the gel-coat? What is the service history of these gliders?
