I need help with Emergency Fiberglass Repair
I need HELP with an Emergency Fiberglass Repair. The vessel has to remain on hook for at least 4 to 5 months.

Currently I am looking at 2 products, Wet / Dry 700 and Quick Fix 2300.

Has anyone tried either of these products or will you point me to others that will seal the fiberglass while holding off on the repair.

Thank you,

I suggest that to get a meaningful answer you probably should supply more information about the nature of the repair and whether the boat will remain unattended. I also have never gotten decent results using so called underwater repair materials.

Jim, how extensive is the repair?
A lot of epoxies will set up just fine underwater the trick of course is getting a "clean" bond to whatever you are fixing. I think I'd be tempted to use a can of self-expanding urethane foam (used as insulation) under a repair mat though. The reason is that urethanes actually ABSORB water as they cure, and the instructions tell you to DAMPEN surfaces before applying them. Which makes me think that if the repair was relatively minor, I'd get a better bond and a patch that was easier to chew off when I did haul. (And conformed better to any voids, etc.)

No way that you can heel over, i.e. put an anchor out the boom or to the masthead, and haul the boat over far enough to work temporarily dry?

Is the repair above or below the waterline? Is the repair structural, or just to seal a leak? What kind of boat is it? Where is the repair located? I think these are all questions that you need to answer before you can get any reasonable approximation of useful help.

I like the foam idea. Another option is a big peice of billboard/banner type thick vinyl and epoxy. Not sure if this would work because I never tried it, but you can purchase epoxy in self-mixing 9oz caulk-tubes. It would probably work if you smeared that all over the offending area and applied some kind of mat or plywood.

Kind of hard to advise with so little info.

The two products you mention are thinner, more like a mastic product. If you need something thicker and more like a putty try: Z-Spar A-788 Splash Zone. I don't know how they recommend removing the Wet/Dry 700 or the Quick Fit 2300 but Splash Zone can fairly easily be removed with a heat gun (when it comes time for the patch removed and the repair to be made). This is important because if you are looking for something as a temporary repair (to get you thru til you can make a proper repair) then being able to easily remove the patch is a definite benefit. Not that Splash Zone cannot be a permanent repair.

Hope this helps, Good Luck,

nelson, the OP is from 2004. One would think that boat is either fixed or sunk. But, you did get the plug in for you business.
