Model Boat Question

I'm wondering how much carbon fibre cloth (and associatedmoulding equipment) i will need to replicate a dual hull model boat i have, itwill need to be strong enough to withstand engine vibration & waterinteraction.

Should i be using just the plain cloth or put through afew layers of your kevlar / aramid weave?ill be putting some pretty fastengines in it & don't want it to..

a) break up under stress of hitting the water or

b) allow water to seep through - is this an issue? i havenot used carbon fibre before? if it is, how many layers do i need to use toensure waterproofing while still keeping it as light as possible?

It is approximately 50cm width x 50cm length * 100mmdepth

I live in Australia and i was wondering what the shippingto here would be - i live at hope island on the gold coast (QLD) the postcodeis 4212,

Thanks in advance,

I think this is a simple question, BUT. I am refurbishing a plank on frame tug, some of the planks have shrunk so i need to coat the inside of the hull with glass cloth and resin.

Hears the difficult bit, some of the areas i can't get at with a brush and cloth, my idea is to pore resin into these areas then rotate the hull to distribute the resin over the inside of the hull.

So far so good. I have been given some of your Infusion Epoxy Resin, with AT30 Fast hardener, it is a bit thick, is there some way of adding 'thinners' to make it run easier??

I did see a topic which suggested warming the resin to make it flow, what effect would this have on the curing time, or would a change to Slow hardener help??

What do I clean the brush with??
