Bottom paint

[Destroyer]

Soda Blasting Jason.. Some ppl use walnut shells with good success, but I've never used them and really can't speak from experience on them.

Soda media, although the same thing as Baking soda that you buy in food stores, is a much courser, hollow grain.. when it's shot at the paint it hits with enough force that it literally explodes,, the force of that explosion tears a tiny bit of the paint loose as it hits... now multiply that by thousands of grains a second and you see why it's so effective. But the media is so soft that it will not damage the sub-strata..... in this case your fiberglass. Do an internet search on Soda Blasting and you'll find many sites dedicated to selling it and the theory behind it. One of the best sites is, (not surprisingly) Arm & Hammer's site.
