[shua]

MB is short for Micro Balloons.

Found the milled glass on OSE what is MB? I assume it's the epoxy I need ,thanks

[MG1234]

Thanks I'll look for milled fiberglass,in construction we acually mix something like that in cement for strength ,

[MG1234]

But it's just cracked on 2 sides and its to far in to reach the inside ,is there a light weight filler I can pour in each tip to that area to help hold it ? Then do carbon work on the outside?

Using the micro ballons as an additive to repair a crack is not the best idea. Micro ballons is used to make epoxy easier to sand and actually weakens the epoxy. A better application for epoxy/ballons would be to repair surface impefections on the outside of the hull so it can be sanded smooth. It is porous, so it will need to be sealed with something.

As mentioned already, there are better additives for strength........milled fiberglass, milled carbon fiber, silica, graphite. For example, I use silica mixed with epoxy (G-Flex) to eliminate sag while the epoxy cures.

I would cut a piece to the close shape in pink or blue foam to fit in side the hull and pre-wrap in fiberglass cloth before final installation. Taper and sand the out side and cover in cloth and use a good quality masking tape to hold in place and let harden. Use a the FG milled and cab-o-seal mixed as a paste to fill and help hold together before taping.

I think I want to fill the tips for strength ,what would you recommend ?

You can use milled fiberglass and MB to do a repair too.

So micro balloons are not balloons at all it's just an adative,I had some idea that they were balloons you insert in hard to reach places ,like the tips of a sponson ,that would help shape the repair ,then once the glass is done you remove them ,so energy of my ignorance ,if I fill the sponsons all the way to the crack which is at the front of the boat ,what's the lightest stuff to use ? I've read so many ideas ,there's that expandable stuff ,or the micro balloon adaptive ,help please

It's just used as a filler to keep the weight down ... Scroll down to "Micro balloons" http://kintecracing.com/Building_Supplies.html and I'm sure you can find similar stuff on places like amazon with free shipping etc.

Is your damage similar to mine ?

[MG1234]

I read that but I still don't understand epoxy balloons ,what or how they work ,thanks
