We just went through this exercise for the very first time and probably over prepped.
Take some photos of the wiring
before unstepping the mast
so you can easily put it together afterwards.
We bought a heap of protective gear
but didn't buy decent rollers or a sanding
pole...we did use the plaster board sanding sheets
and found them way better than the sandpaper. We didn't use a power sander, wet sanding by hand wasn't that bad. We should have got ourselves a buffer for the top sides paintwork though.
On protective gear
...we were surprised how many other people were sanding anti foul in shorts and thirst with no protection...
We had 5 days on the hard
stand and lived aboard. That was long enough...glad to get back in the water
We also replaced the head
pipes while we were out, pretty simple job but a bit smelly.
