Larry,
Abrasive blasting might result in an uneven surface due to hard and soft spots. I have done a lot of sand blasting on my ferro hull but have used only sand. I buy it in 50 lb bags from Home Depot or Lowes and use a siphon style blaster with a three HP compressor. It is not nearly as much power as I would like.
I did once rent a big commercial diesel compressor and blasting rig to blast my entire hull inside and out after curing the hull and other than hassles due to single-handing it, I was able to blast clean my entire 63' hull inside and out in one day.
A belt sander would produce a more even surface, but would be hard on the arms. I really like the machine I have, I can hold it in one hand if I need to, but am not home right now to give you the brand and model.
You might try a low speed (600 rpm rather than 6,000 rpm) disk sander. A very coarse sandpaper with light pressure might help with the debris loading-up problem. Maybe a air blast to knock the debris out.
Perhaps some grunt labor would be a good investment with this project.

Don,
You made it to NW Wisconsin..been very quiet until now. Everybody must be paging through their new West Marine catalogs, trying to find the solution to a few problems on their respective boats.
I'll pose a question for all to ponder and help me out with. I'm removing 17 years worth of Micron CSC bottom paint..mostly ablated already, thru use and also a power washer. I now have a evenly brown and beige bottom, truly ugly. I am considering a sand blaster rental, using crushed shells or??? Is this a good idea, or would some other method be better? (One ocncern for me is that I am recovering from a torn rotator cuff from a shoulder dislocation, so have little upper arm strength now, but it is coming back gradually -this goofs up using a large right angle grinder on the remaining brown bottom paint for any lengths of time)
What material is readily available and sufficiently gentle to get the old paint off, but not remove the gel coat under normal use.
I was thinking of using a sharp scraper on a wooden extension handle, might be hard in my situation, but possible.
Cheers on the 2007 Season! Let it begin
