Default Reprofiling LS6 wings

Okay, I think need to be an idiot and ask the questions (I beg your

I understand the part about getting the correct profile templates and
shaping the wing to the correct profile. *However, doesn't that mean
that the wing will be thicker than profile once the gelcoat is sprayed
on? *Or are the templates made deliberately thinner to account for
this added thickness? *But then how would one know how thick to lay on
the gelcoat?

It seems to me that "re-finish" and "re-profile" are being used nearly
interchangeably, i.e. in both cases, the gelcoat is completely
removed.

Can it be that the gelcoat can be only partially sanded off, filled in
somehow (more gel?) to meet profile, then bond in another layer of
gelcoat? *I've seen a wing repaired: new foam core, glass layers,
bondo then gelcoat, so I know small patches can be done this way (I
didn't get to see the gelcoat being applied).

The best step-by-step I've ever found was on Jimphoenix.com. He
stripped, reprofiled, and refinished a set of Nimbus wings.
Unfortunately, I don't think it's still available, as he has moved to
Washington and is now more into boats. It might not hurt to email him
to see if he could send you the 'article'.
