OK guys. Thanks for the comments. I'll do my best to answer any questions.
We did a fine sand on the primed smooth shiny bits with 400 grit wet 'n dry. this was
only for the white Perfection.
We removed any insects or debri from the prime coat with a razor blade.
We vacuumed any dust off with a household vacuum cleaner powered by an
inverter. Before applying the topcoat we wiped down with a rag made from
tee shirt material. Use a white tee shirt because this paint is so strong that it
seems to leach the colour out of the cloth.
We did not wipe down with any solvent, like International 10.
You need to use the BEST brush. We found that the Deco brushes from Aldi were
better than the Badger hair brush from Whitworths.
Missus painted like an old fashioned house painter, diagonal strokes one way, then diagonal
strokes the other way followed by vertical strokes from top to bottom.
Only one top coat applied (not thickly). A top brush will leave faint marks that seem
to disappear over night.
Being on a swing mooring limits access to areas of the boat until previous coats are
dry, so there was no rush from us. You also have to work around the weather.
So the undercoating took 5 days and the top coating 11 days. All up. Including taping,
cleaning up etc.
We did not sand the dimpled areas for the non skid paint.
Yay! Finished all the painting. Just thought that I would post these pics to finish off the thread.
Great stuff! Now I'm inspired to look at moving from oil base (for the areas I can take back to the sheathing). Well done!

I am wondering how much time do you have after you brush on the two pack perfection undercoat before the top coat has to be applied?
I was lead to believe is was very short.
This has been a pain for me being a weekend warrior 
Yes HG, I can well understand the concern, this stuff is expensive and you want to get it right.
We tried our best to get the top coat on within two days of undercoating. The paint takes about
twenty four hours to semi-cure and that's an ideal time to top coat, which we endevoured to do
with the white shiny bits.
We couldn't however achieve this with the non-skid areas and in some cases it was the best part
of a week before top coating. But there was no problem, and as you can see, it all turned out OK.
I don't know if being under a tarp delayed the curing so top coating could be applied later ( I suspect
this might be the case ), but as I stated earlier the tarp was to keep off the dew
Missus and I have been able to go every day weather has allowed and that has helped a lot.
A windy day is a no no. Especially when, like us ,you are on a swing mooring and you paint the side
decks standing in a dinghy hanging on to the lifelines. BUT, it can be done. We've proved it.
I don't have to tell you HG that wind will pick the paint off your brush and blow it all over the place.
With this paint, once it's dry, you need a jack hammer to shift it..
So clean up as you go.
