GL: Bottom Paint Stripping

[Rob Zanussi]

Blasting can use any medium. Sand, walnut shells or baking soda. It all
depends on what you are blasting. I have used sand on the steel hull of my
boat, walnut shells and glass marbles on the aluminium valve covers on my
68 Shelby and baking soda on the body panels.

The advantage of baking soda or even walnut shells is there is no
distortion to the metal. Whether baking soda would harm your gel coat or
not I can't tell you. Perhaps contact a blasting shop and ask them. They
have also used high pressure water to remove paint from car bodies.

Do you realize that in about 40 years we will have thousands of old ladies
running around with tattoos and pierced navels?
