I do use a wheel buffer on the first step but it can all be done by hand to. I'd recommend a obsoleting buffer if you've never used one before, less chance of buffing through your gel coat. There are a few ways to do this job, this is just the way I chose to do it.
This is very close to what I have done... on my boat. At 42', it was a major chore that took me the better part of 3 days. The result is an incredible glossy finish that lasts a long time when the right wax is applied.
Over the years, I have found the best results and quickest work by using a Porter Cable 7424 buffer with foam cutting and polishing pads. The combination of this buffer and the foam pads eliminates the risk of burning your gel coat.
I get a full year out of my wax job in the central Florida sun and salt. By using Collinite wax, the sun and salt are held at bay for a full year! Diesel dust from the exhaust just rinses right off. I use their liquid wax (No. 925) for the large areas and hand apply their paste wax (No. 885) in smaller areas.
I've done this to the boat a few times over the past 10 years. PM me for any additional steps or questions.
No, I don't work for Porter Cable or Collinite.
