Dear all,
thank you very much for your interest and your comments!
Bo, Stephan, Juan and Stephen, the more I look at the photos the more I have to agree with you. Shaky hands stay shaky... I don't know why I didn't get the idea to use decal paper! I had the idea to buy a yellow marker that should draw lines up to 1mm. But its cap was sealed at the shop, so no trying out was possible. And when I tried it at home it was more about 3mm in width than 1mm (which would in fact still be too wide). The product available via the link you've postet, Bo, looks much more promising.
But I think when I take the outlines of the Motorcycle parts with the help of masking tape, transfer them to cardboard and use this as a pattern to draw the lines on clear decal paper, which can be trimmed using a sharp knife, it should work - at least better than painting thin lines freehand...
Best wishes
Borsos
BTW: I am very grateful for your constructive critics. Sometimes you know something in the back of your head and you just don't want to accept it. A little shove from outside is really valuable then
