Been lurking on a couple of different sights/forums to gain info and my nerve to tackle my own build. I came across the process below on an Aussie site and performed a copy/paste. Hope the original poster won't mind, just thought it'd be helpful info to square up the bottom edge of the transom. PM me if you want the link to the other build, not looking to ruffle anyones feathers.
The reverse chine is made from a combination of epoxy, flock, glass powder, cabosil and wood flour. A balsa wood and /or cardboard dam is glued onto the hull with C.A. then the mixture is trowelled into place and shaped. After it has set off a bit a mixture of Q cell and epoxy is trowelled over the top to allow for fairing to shape. The base composite mixture is very very hard to sand so if there happens to be any high spots which really should be avoided they can be ground down with a grinder. The cardboard and balsa just sands and chissels off.
It is really not to difficult to do and does not need to be glassed over. Make sure you rough up the substrate with 40 grit before you start.
I intend to make the strakes and skeg the same way. I will put up photos.
To make the glass powder lay up some scraps of DB (Biax) fibreglass onto some spare wood let it cure. Then, up it with the belt sander (40 grit)...Collect the glass and there you have it. You will need to wear protective clothing unless you like the glass imbedded in your skin and lungs.
Miyot, exceptional work & craftsmanship!!
