Body Filler

[sedelange]

I was performing fiberglass repair on the bottom of my boat and found a few blisters.  When I opened one of the blisters I found what appears to be body filler (Bondo).  This blister is about an inch above the prop strut.  Does anyone know a reason for there to be body filler in this location?

Steve : It almost sounds like a PO used "Bondo" to fix some previous blisters rather than an epoxy filler!  That's my guess.

That was my thought.  I just wanted to make sure before I ground it all out.  There appears to be quite a bit there.  I just don't like bobdo on a boat.

and if you had bob dole, no telling what might be sticking out where!!!

You may want to cut the PO some slack.  The untra light filler used in epoxy haas that same red/brown color as bondo.  It is used to fair out epoxy repairs.  The factory may have used it.  It isn't water proof and without a barier it would form a blister.
