I am an advocate for weathering not cooking. Weathering is exactly as Craig mentioned....cooking was a process used some years back to help erupt air bubbles under gelcoat. Excessive cooking led to unequal stresses (different thickness of layup) causing severe shrinkage of some panels.

I am also an advocate for letting any repair/fill settle/cure before final finishing.

This last step is important....How often do we see a newly painted cobra and it looks beautiful. Three months later we see the fill regions and imperfections starting to show?.

Get it nice and fair...seal the filled areas..and let it sit as long as you can...then resand, reprime and paint..
