I'm deffinitely not an authority on this, but I'll give you what I know.

PPG Concept is much more forgiving than Awlgrip. PPG is more like Imron. Alot of fine custom builders use PPG Concept. Gel coat is very difficult to get a good job since you are dealing with a thickness build-up issue and a material that doesn't flow out well.

Paint sprays out very thin, say 1-2 mils per coat and you put about 3 or 4 coats to give a total thickness of about 5-6 mils after all the sanding between coats. Gelcoat needs a good 10-15 mils or so of thickness to hold up well. Building that kind of thickness over a large area leaves alot of room for error/low spots. Not to mention alot of finish work after the application of the material.

Ther are some good additives you can use with gelcoat now that will aid in getting a better flow of the gelcoat when sprayed. Duratec hi gloss and patch reducer both work well in getting a smooth layer of gelcoat.
