Hi all here is an update on this one
Hi all as a note People keep asking me how I do these sails, well here is a short guide, they are so easy.
First you need the white spirit you clean your brushes in ( you know the jar or bottle or whatever that all the sludge builds up in( I keep mine topped up in a little bottle as I use it for other things too)
you get your vac formed sails , your brush and your white spirit.
then you get a good brushfull of the sludge in the bottom of the bottle and scrub it all over the sail(both sides)
allow it to dry and give a second coat if required
then with a downwards motion wipe the muck off till you're happy with the effect
and there you are, see how easy it is.
