Refinishing: Who has tried a shortcut?

I have refinished an old Mosquito that had badly cracked
wings. I did it with Glasurit 2K and high build epoxy
primer.

We took off enough old gelcoat that the surface looked
good, we did not remove all old gelcoat.

We took lots of time removing grease/oil/dirt from
cracks in order that the paint surface would not be
damaged by grease causing the paints not to stick well.
Used lots of degreasing agent, acetone I think.

The epoxy primer took very well and was sanded back
for smoothness then painted with the top coat 2 pack.

I haven't seen it for a couple of years but last time
I did the paint was still holding up and not showing
any signs of crack propagation through the primer and
top coat.

When it was finished, I was very pleased with the results
and the glider flew much better having got back a great
portion of its laminar flow.

The gelcoat, although cracked, was NOT peeling off.
It still was a suitable surface to paint on.
