One of the main reasons our gelcoat gliders crack up is because of the =
final finishing process. Boats are popped out of a shiny mold and are =
basically done. Glider pieces that are gelcoated get additional sanding =
for contouring, etc.. This breaks up the surface gelcoat which, at the =
time of process, has additional "protective" cross-linking at the =
surface. This is great for contouring, but a no-no for finish =
longevity...unless you immediately paint over this surface with poly =
paint, etc..
I have noted several gliders that were refinished with poly paint where =
all of the old crazing was not removed. One $10K, 2-seater refinish job =
has cracks returning after 3 years.
