Has anyone ever used Bondo-Glass to fix a fiberglass Hobie hull? I've got a couple of small cracks in the bottom of the hull which allow the boat to take on a minor amount of water and was wondering if this Bondo product would work. It appears to be easier to work with than a fiberglass repair kit.
We're repairing seven Sabots that have been used for a junior sailing program. They've been abused for about four years and have lots of damage.

We've found that using a tube of one part Bondo works great for scratches. We are applying paint over the Bondo.

For damage where the hull has been dented or punctured we're using two-part Bondo or two-part Bondo with fiber in it.

We had a couple of places where the damage had been bad enough that we removed what foam was left and used Great Stuff insulating foam to fill the void. After it set we shaped it, filled in the small holes with Bondo and glassed over it. After sanding and paint it looked just like new.
