People (Tim?) say board sanding is good but if I was also to buy a power sander what would be the most useful for hull preparation?
Or do I go down the board sanding route?...and if so can someone (Tim?) post something on the finer points of board sanding - size/thickness of board, grades of abrasive, virtues of wet/dry.
Would a belt sander do a garage door well? (Trying to multi-task)
Random orbital is a phrase that sticks in my mind from previous threads...
As you can see I have led a sheltered life...sheltered from real work that is :)

Random orbital is the best. Belt sander is too aggressive for little gain. Normal orbital is Ok, but go big and powerful if you do. For numb we used a combo of 40 and 60 grit on a deWalt random orbital and it still took ages. The first bite of the paperv is so much better than the following 5 minutes! Also, use the vac. Less mess and keeps the paper working better, longer.
The long board I used was about 3foot long and was a bit flexible. I only used it to fair what I had sanded by machine.

Spot on Tim! We find Metabo random orbitals to be the best

A high quality of sandpaper also helps. There is a grey paper called production paper (I think?) that is very good and makes the job soo much easier.
