CLEANUP AND STAND BACK!

The good thing about polytarp is that overspray doesn't stick to it either.

A damp rag, or a rag dampended with mineral turpentine is fine for cleaning up any overspray.

You can even twist it to a point and tidy up the edges of your work, using it the way your mum used a handkerchief to wipe the spots from around your mouth.

Stand back and admire your work. Be careful of the gathering crowd. Be nice to them, pose for photographs and sign autographs.
