Emrone (sp) is commonly used on boats and would save some money. If your looking at a complete restore and paying people to do the work then it will be very expensive. If your going to spend the money for a paint job I'd also have the flooring, transom, runners etc, checked before sinking money into the paint job.

Imron is cheaper than Awlgrip, but not by a whole lot. PPG and BSAF have some new industrial coatiings out now, that promise to cut down on prep time. I used to work for an equiptment manufacuture that used anti-graffiti Imron on the trucks we built, you couldn't get spray paint to stick to it. I always thoght it would make a good bottom paint, never had a chance to try it.

even though awlgrip is rock soild. i have interlux bright side on my hull and it being ancient it really looks good after a compund and wax. also the paint isnt really that expensive and the primer is fairly inexpensive too.
