Random Orbital every time -slow but sure-but watch out for sharp edges-I just destroyed a pad of an almost new orbital sander by catching its edge against tracks and various other bits of metal.

Unless you are Moses, keeping your arms above your head for hours, especially weighted, would be very difficult to get a good finish. Belt sanders are heavy and the belts start moving around after a while causing other problems.

The belt sander I've had for 30 years I don't even use it anymore except up-side-down to flatten small pieces of wood or plastic.

I second the peel-away! Peel Away® Products

I have a Festool Rotex RO 125 5" dual mode sander. It combines random orbital with rotary orbital motion and removes paint much more aggressively than a common orbital sander. It is far more practical than a belt sander - and nearly as effective. Festool has a wide range of papers suitable for paint removal -as coarse as 24 grit.

I use it in conjunction with a Festool CT-26 vac for dust extraction. Over 95% of the dust goes into the bag, and the paper never clogs up with melted paint. It's a hefty investment for this combination but it gets plenty of use at home as well. Such as stripping lead paint from cedar shingles. So in my case the investment was justified by saving time. Factored into this - cleanup time, responsible disposal of the paint dust and compliance with the EPA Lead Paint Law that became effective in April 2010.

I have used it on my topsides, which were overdue for repainting, but not on the bottom, which I would not care to strip with any sander or by any other means on my old wooden boat. I'll stick with my ablative paint.

Woodcraft Supply retailers have the Festool line set up in their stores for demonstration. You can bring a painted board to a store and try out the system yourself.

The chemical method sounds like a good idea. I just did our Cat 25 and used a DA air powered sander with 80 grit. Worked great!

Spent two 5 hour days and another 3 hours the last day.

After two days scraping then the 3 days of sanding it went from this


To this

Now the blisters are all repaired and ready for 8 coats of epoxy barrier coat and 2 coats of hard bottom paint.
