Default Fiberglass keel repair & damage prtection

Hi all,

I'm wet sanding the scratches on the hull of my 19' fiberglass hull (mostly
on the underside along the keel) and I've noticed that a few of the deeper
gouges have gone all the way through the gel coat, showing the charcoal gray
of the fiberglass underneath.

My first question is- what is the best way to fill the gouges and deeper
scratches, and what coating should I put on the repair to help it last?
Would some sort of barrier coat be tough enough to withstand occasional
beaching?

I've also heard about a PVC "keel guard" product that looks interesting,
albeit a bit expensive.. Any thoughts from those who have experience with
this product? Can it be applied over existing gouges, or should repairs be
made first?

Lastly, how does one check to make sure that water has not penetrated into
the fiberglass layer?


Thanks in advance.

Take a look at this URL and get a feel for what you are going to do.

There area a couple of keel guard products out there, but I use
Hamby's Keel Guard on my Ranger - I don't use one on the Contender.
The Ranger occationally is beached, bumped on a ramp, that sort of
thing and works great.

You will probably have to go past the actual gouge to see how it
looks. That could be problematic if you don't have fiberglas
experience. Water can wick up fiberglass, but it usually won't go
past the original intrusion unless it's really, really bad.

One guy I know has worn the whole front of his keel down to the glass. As
long as you're trailering having the glass in the water is not a big deal.
I'd fill it with gel coat or resin before covering it with a keel guard.

There's nothing you can paint on that'll work, however, 3M makes a plastic
sheeting that aircraft use on their nose radomes that is tough as all hell.
I'd give it a try, but I bet it's not cheap.

You should always repair the damages first.

the fiberglass layer?


A moisture meter, check with a surveyor, he should have one.

I had a similar problem. I'm lucky to live in San Diego, where it's pretty
dry and the hull of my trailered boat dires out well. I learned how to do
fiberglass repair - it wasn't difficult, then sanded it to get the surface
smooth before applying Keel Shield/Guard. That was easy, too. Now I can keep
beaching without worrying about it. Had I known, I would have installled the
Shield when I first bought the boat.

Stanley: the Keel guard is a great product yes it cost.. but compare to gel
coating.. its worth it i have one on my little Hi-laker. i would make some
simple repairs to it just to full in the Gouges.. But i warn you don't rush to
get that thing on.. once you stick it.. its ON.
