In all five coats of varnish were applied to the transom and rub rails.
When fully hardened I went through the (by now) usual sequence of wet sanding and finishing off with polishing compound.
This is the transom after wet sanding from P800 through to P2500.
And this is what it looked like after being treated with polishing compound from P5000 to P11000.
This is the polishing toolkit.
It consists of the Rotex 90 sander set to rotary mode and fitted with a special polishing head and a foam pad.
Polishing compound (effectively liquid sandpaper) is applied to the pad and the surface is moistened with finishing liquid.
The surface is then gently polished at slow speed, going through the three grades of grit; P5000, P9000 and P11000.
The results were excellent - smooth as glass and very shiny.
I moved on to the rub rails. This is the port rail wet sanded with P800.
And here is the finished rail.
You can see from this close up of the rail at the port quarter that it turned out very nicely.
I'm happy with that and I am now confident that the spars will all look great when treated the same way.
