Problem with Awlgrip is that it's not easy to patch, Neither are Perfection or Brightside; but at least they're cheaper and easier to apply. I did my hull using Primekote (2-part epoxy primer/barrier-coat for Perfection) and then Brightside over it. It came out really well, though I have a few more spots to redo come spring. I would recommend this scheme to anyone on a budget.
I would not attempt Awlgrip except in a professional-quality setting (indoors, dust-free, efficient spray equipment, expertise). The beauty of Brightside, and to a lesser extent, Perfection, is that they are easily applied by the boatyard amateur by rolling and tipping.
There is another Awlgrip-like product which I forget the name of but it's not recommended because it's even less repairable than Awlgrip.
One caveat to Awkgrip-- you CANNOT buff it with compound. I would use nothing stronger than PTEF products on it. Once you abrade into the finish, it will become porous and gray, and then you'll need to chemically strip (most of) it off and redo it. This has happened many times to unsuspecting owners (the ilk I refer to as 'boat polishers', since that's all the maintenance work they ever do to their boats).
I posted some details about this on my blog.
