Hello
Sorry just came across this and thought i would add to it. Little Jo's painting article should cover most of your questions however here is a little tip. As a rule
I would
allways paint vehicles with spray paint, carefully taking them apart and painting each peice seperatley. I am pretty sure it would be impossible to get a perfect 'brush stroke free' finish doing large vehicles by hand. As for klickies the best method is painting them by hand, however i rarely do this so i dont think i am the best qualified to offer any advice
A word of warning though and just to reiterate what Gordon has said. It
is impossible to take your particular helicopter apart without destroying it or damaging it. Carefull masking and a lot of patience would be the only option if you wanted to repaint it, i have seen this done, so it is possible.
I hope this helps you in your quest to re paint your Playmobil,
Tim
