I would like to try a graphite/epoxy bottom on a new build. Should I do the standard 3 coats epoxy then graphite mix? Or could I do one coat epoxy to cover the fiberglass and then go to two coats of the graphite/epoxy mix?

RE: Graphite
I am pretty sure I know the answer to this already, but here goes: When using graphite in epoxy like in the above posts, is it still necessary to apply a UV protection layer, like varnish or paint? My guess is yes, but one never knows....
RE: Graphite
My plan, should Laszlo choose to accept it, is to wet out the glass. After 8 hr. periods I will apply coats to the sides which I want bright. After a day or so I will put on the fine line tape and proceed with steps 2 & 3.
Is it okay to let the bottom hull cure for a day while I am working on the sides?
RE: Graphite
Interestingly enough, I just used graphite on the bottom of my passagemaker and did it pretty much the way that laszlo described except that I didn't use microballoons when filling in the weave. I simply used two coats of clear epoxy and then two coats of the graphite epoxy. So far, it has worked out great. but, I only launched her a few weeks ago.

On my WD12, I did the following:
1. Wet out the glass
2. Fill the weave with a microballoon/epoxy slurry
3. 2 coats graphite/epoxy
Fine line tape for the edges, no sanding between layers. It worked out well.
