In the Spring of 2006, we used 'dry ice blasting' (as demonstrated in
this video) to remove the bottom paint......job was completed in 4
hours.....hull cleaned right to the white gelcoat ....no further work
required, other than a quick wipe down with a solvent to clean before
applying the barrier coat(s)...all 7 of them.
Don't know why this isn't used more often?

I got adventurous this year and decided to remove as much of the existing
bottom paint as possible. There are many layers on the boat that have
accumulated over time. Ordinary manual scrapers take a lot of time and energy,
and sharpening. I developed this scraper which will fit in any reciprocating
saw and uses a carbide blade. It is a lot easier and quicker and the blades
last much longer than regular steel blades.

Now, all I have to do is get at it as soon as the rain stops for a few days and
the temperature becomes bearable.
