Graphite powder to Epoxy mixing ratio?

[TradGlenn]

I am going to be doing the black bottom on my boat and can't remember what RAKA said the ration mix was for the graphite to epoxy.

Anyone know?

I use 20 percent graphite to mixed resin. - one part graphite to 4 parts mixed epoxy

Thanks Mick I think that is what Larry from RAKA said also.

Will start on that part of the build tomorrow or the next day.
