Awlcraft roll and tip suggestions.

[3 Squids]

Ok so most of you active members have seen my new new bright green project. Although the finish doesn't look bad, me and the wifey have come to the conclusion that she (the boat, not the wife) needs to be painted. I've looked into it and it seems the Awlcraft 2000 seems like a good product. I've watched a few videos on rolling and tipping and it seems to be a good way of doing it.

If I have the ability and equipment to spray the hull would that be a better route than rolling and tipping? I've painted plenty of cars so laying down a nice smooth coat shouldn't be a problem. So what are advantages to rolling and tipping.

Also does anyone know approximately how much paint I'd need. It's basically just from the water line to the gunwale that would need painted. Thanks for your input.
