Scary concept. Working time is about two minutes, it claims five but that ain't so if you want a smooth fillet. So it would be tricky but maybe just possible if you moved really fast. I predict a messy nightmare. It is super strong by itself. If you really want glass in PVC I'd look at sanding it to 60 profile, bonding it in with methacrylate, sanding the fillet, and then glassing with G Flex or one of the other new West products and some boat cloth instead of matt.

Re: Nauticat 52 Refit

We use the Permatex plastic weld or Devcon 14320 along with a old dental gun to apply Weldmount plastic cable ties around the boat. I didn't want to spend the big bucks for Weldmounts system, and found these after a bit of internet searching. I haven't found any generic version of the tie mounts themselves, but JMSonline.net has them pretty cheap anyway.

Plus you can use their cool studs with 500 pounds of strength:

And these straps:

Yes, plastic tanks. Very few things will bond to these. Note on the list of things it will bond too are both fiberglass and PVC. It bonds really bomber. You need dynamite to get this apart.

Yep, those are what I started using Plexus for. Permatex is much cheaper.

OK good. No plastic tanks onboard, none anticipated. Thanks.

Could these be used as a possibly easier way to secure, for e.g., a new fiberglass tank hatch/lid?

I used these with good success for a new run of 3" ID wet exhaust hose along the inside of the hull. Just have to make sure you grind down the bilge paint and get to clean laminate.

Re: Nauticat 52 Refit

Those studs would work great.


But consider I used 38 studs for my lids, and those are $13 a pop. That's a lot of money for studs. The way I did it cost about $25 in materials.

Isn't it 15 to a pack?

Re: Nauticat 52 Refit

No pull, just asked nicely. I think? There is just to much good information in this thread to let it get lost.

So, thank you for all the time you have spent documenting your refit.

Re: Nauticat 52 Refit

Minaret -- during your tank rebuild, you discussed using various types of glass cloth as well as mat. By the latter, I assume you mean chopped strand mat. Woud you mind briefly describing when you would use one vs. the other? Are there types of mat that are compatible with epoxy resin vs. the iso that you used? What goes into your decisions to use different wgts. of cloth?

I'm obviously new to this world so excuse the elementary school level questions. Or is it kindergarden level??

You get a bladder of the approximate size, insert it in the tank/space, and inflate a balloon inside of it to make it conform to the shape. Then you heat it to make the resin kick off. Once it starts to kick you can pull the balloon out and put a heat lamp inside to cure it. Voila, insta-tank! Only done it a couple of times, don't remember the product name. Believe it's been discussed on the forum.

That said, it only cost me a few hundred bucks in materials and a whole bunch of time to do mine. You considering doing yours in place because it would be too hard to remove? A regular bladder is not so bad for water, at least if there is a total failure it won't make too much mess. If you use the original tank for a mold it just needs to be really clean, you don't really need the glass to stick to the original tank. That bond will fail before long anyway. You are just using the original tank as a mold.
That does make sense. Thanks for the insight. I have never really liked bladder tanks. I guess I need to figure out how to get better access to the tank. At the moment a 15 inch inspection plate is all I have.
