I guess a different mat is not really the best way to word it . I believe that only "some" mats are supposed to be used with epoxy resins . Something to do with epoxy resins not having styrene to break down the stuff used to hold the mat together . I am not really an authority this stuff , I just remeber having heard something along those lines from someone . IN other words , do your own research .

Here is a small write-up that says the same thing  :smile30:

No kidding Brett!! Lol.

Thanks for the link SPD. The author states to use two layers of Matting followed by a layer of cloth. I like that idea.

Cliff I have a source for cloth too if you want it.

So there is a difference in cloth depending on using Epoxy or poly resins?

Where's your source? I planned on just going to Homey Depot for it.....

I am not using mat because of the strength of Epoxy.  I did read the article SPD posted the guy there talks about using epoxy but then doesn't distinguish the difference in mat.  Regarding cloth there is no difference in use with poly or epoxy.  The reason the difference in the mat is like SPD said that Poly has styrene that breaks the bonds of bonded mat so that the mat can conform to shapes easier and epoxy doesn't have that added and its not a good thing to add styrene to epoxy as it weakens the epoxy bond.  Styrene is what makes poly resin eat through styrofoam cups.  Hope this clears that up.  Your welcome to get the fiberglass cloth from Home Depot I never saw it there.  I had bought mine last year from a selller on ebay but looks like he has used up his source.  Here is another source on ebay:

This is 24oz I have 20oz that I am using in my boat.  One layer of that and a good coat of epoxy will be plenty strong enough.

One thing I want to bring up is Cloth the heavier the cloth the stronger it can be but the more resin it drinks and the harder it can be to saturate and roll out the bubbles.  Good thing about epoxy is it gives you hours of working time versus the minutes with poly.  So doing a large area at a time if worked in the right direction is totally possible.  From what I know that cloth will drink its weight in resin so 20oz cloth is 20oz per square yard will drink 20oz of resin per square yard.  So you can plan on that as a measurement starting point with your resin.  If you saturate the cloth properly you should feel the weave in the finished hardened product.  Good thing about epoxy is you can go over it and level it out without the need for additional mat or finer cloth because of the strength of the epoxy.  With Poly to smooth it out you have to use a very fine weave cloth or a layer of mat on top and grind the mat smooth.  me I am just going to put my rubber backed marine carpet on it and call it done.  Darn that's another thing I still have to buy.

The difference in cloth can play a big part but mostly look at the weights.  Once its epoxied it will be plenty fine.  The strength of the cloth really plays more of a part when using poly.

Just do it all with carbon fiber and leave the carpet out  :smile30:

LOL he would have to change the name to "unbreakable" or "no expense spared"

It's actually not that expensive to use the carbon fiber instead of fiberglass mat . It would look awesome to use it on the stringers and just carpet between the stringers and the outside of the stringers . Just leave the stringers exposed .

Not with Ford power.
LOL i didn't say it should be called "Won't Break Down"  maybe should have said it should be called "Unbreakable Hull"

SPD carbon fiber provides a similar weave pattern to the cloth its just the coloring that's different but it would be super strong.  Imagine making Carbon fiber Rectangular tubing stringers?  They wouldn't need a wood filler and wouldn't rot out and be stronger and lighter.  Hmm new idea for next project boat.  Why not just make the entire hull from carbon fiber no need for stringers, muhahahaha.

Just get it back together Cliff. All the ideas are great and any choice will be better than what came out. They'll all last longer than you'll probably own the boat so just get er dun!! The stringers in both my boats are wrapped. You have an engine cover so you don't need a super pretty set up. Glass it, paint it, get the motor in back in, cover the rest in carpet and get back on the water.

Just got a call from the engine builder, Wayne Calverts.... $1,700 for my engine rebuild.

I think I'll modify Matts signature statement..."There's no such things as an Inexpensive boat". Lol

I was really just kidding about the carbon fiber . It would be cool in something like my boat where the bottom of the boat is the floor , but it would be a huge waste in the Crusader with a floor over it . I agree , wrap the stringers in glass and get it put back together . Summer is here already , no time to waste .

That's the plan James....going to build and install the new stringers and floor next weekend 5/6/12...  In fact, I might even miss the NTJBC season opener just to make sure my boat is good to go.
