The gelcoat I referred to is not air inhibited and it didn't cost any more than regular gelcoat. It is handled and sprayed just like usual - thinned with acetone etc. You can even use those disposable Preval sprayers for touch up purposes.

I think the problem with it is what has been said in this thread - most people think it's only good when sprayed into a mould before laminating, otherwise it's too much work.

2 part polys have attained the image of being the only way to go and it has become conventional wisdom as a result.

That isn't true.
