I have discovered the link below about launching and model set up, Joe Wurts and Darrel Perkins both contribute......quite interesting.

PAINT!!!
Well....what can I say, I have trawled the Internet trying to find a definite solution to laying up on the cured paint, there seems to many solutions but also many failures. I took the decision to remove the paint from the moulds and start again with the new painting technique to be sure of a perfect finish, after all everything else has been done to exacting detail.
I thought I was going to get up to my elbows in thinners and sticky paint residue, but after picking at the tip I found that the paint was lifting out the mould so with a careful pull it came out the mould in one piece. Well...............that release agent works very well.
On the positive side it gave me the perfect opportunity to weigh exactly the amount of paint that goes on to the wing/tailplane............very interesting.
I have ordered an air fed paint mask which should be here next week, this 2 pack paint can kill you! When it arrives I will start again..............although one step back we have made ten steps forward.

More Weekend Progress
What a busy weekend I have worked it out to be Friday night 5 hours, Saturday 16 hours and Sunday 7 hours..........
It was great to have company and Andy and I really got stuck in for a marathon session, there was plenty of beer to drink and lots of hard work. Although we did not get the cloth in the moulds we are 90% there, we seriously forgot/underestimated the time it takes to spray the moulds. Never mind, we did not cut any corners and are confident this will be a great model.
The new release wax is a delight to work with and is super efficient, so much so that we had a little complication spraying the moulds, we encountered the dreaded 'fish eye', this was overcome by reducing the paint output and increasing the air but since Sunday I have been doing some digging around on the world wide web and found the following link which also advises to change the spray pattern from circular to fan at a reduced air pressure, allowing the thinners to evaporate before hitting the mould surface resulting in a thinner/dryer layer of paint and the chemical in the thinning agent not attacking the release wax.....

I now aim to get the tailplane laid up by the weekend with the wings probably next week.
