Before anyone says it...I know this info is posted elsewhere here and I appologize for the new thead if I've committed some hienous sin by doing so.

That said, I'll ask for some advice. My starboard hull is soft from in between the pylons. It doesn't appear to be all the way to the pylons but sjust short of them. I AM going to attemp the repair (no question). I 'd like to know just how large a section should be attempted at a time? Can I work more than one section at a time?. Please keep in mind I don't plan on racing this boat...she's just a toy for weekend play. Any and all advice is appreciated.

here's the link

I've only done this once and found doing big, or multiple sections, at a time is not the best idea. Do one quarter of the area first to cut your teeth on the process.

Small areas / small batches of resin.

You will be injecting into the void between glass and foam layers.

Two big issues that limit the size of the area:


1) The resin will start to cure unless you reduce the catalyst, but then you risk it not kicking at all.

2) If you hurry because the area is large, the more pressure you use the wider apart you force the layers. A) you end up with a thicker resin layer or B) you get a lot of the resin oozing back out due to the layers of glass going back to normal position.


Do it in the shade, cool. Do smaller areas to make it easier on yourself.

mmiller, have you worked with that git rot stuff? do you recommend it? a quick search of the stuff yields wooden boat repair forums and the label on the bottle says its for wooden boats. but im assuming it does the job well on filling the fiberglass void?

Thank You Gentlemen,

OK, Small areas, got it. Work progressively, section to section, allowing time for each section to cure before moving to next section? Is this a good area to install an inspection/storage port, or am I wasting my time and potentially weakening the hull doing so? Part of my thinking here is allowing access for inspection of the stancions and repair if necessary (this is precautionary only...I can't detect any movement or play in these components).

I have the publications as well as the DVD from West Systems for making the repairs, I'll have the help of my partner in the boat, I'll review that material a few times before starting the repairs. What I'm looking for I guess is the experience and advice of the salts in the know. Books can only tell ya so much. Thanks so much for the help.

Any one nearby that would like to come by and offer advice/assistance is welcome. I'll be more than happy to provide contact info and hot/cold beverages for anyone interested.

Yep... I have used it and recommend it.

What makes this a good choice are several things.

It penetrates.

It does not harden to a brittle structure. It is a laminating resin and remains a little flexible.

It is easy to work with.

So, would I be better off using Gitrot vs West Systems? I'm a little confused.

Yes, especially doing this the first time. The kit is specifically designed for this repair and EVERYTHING you need comes with the Git-Rot.
