thanks for the reference, i havn't got that one in my paint box, so i'll get some asap.
the soft plastic figures benefit from a coat of diluted PVA glue(white school glue) or acrylic varnish. be careful of the moving parts. this then gives the enamel something to bite onto. i paint my airfix figures this way and the paint stays on a lot better.
car spray paint also works but obviously the colours are a bit limited to painting reds

and blacks

with some possibilties for yellows and blues

you need to experiment as different manufacturers have different paint recipies
hope this helps.................forever
