Paint pen for lexan shell?
 

I need buy paint pen suitable for lexan/polycarbonate truck/car/buggy shell instead of using spray can / compressor based spraying for details.

Is there a such thing?

For rivet heads I just use a sharpie/permanent marker pen then paint over the top ...

Tamiya used to make one, I don't know if they still do or if you can even get it.

What's it for ? Can you not just get some masks cut ?

If you want to do the detailing around the windows you can spray your first colour onto the shell. Once dry and backed cut with a sharp knife the outside few mm away of the windows masks away then spray your second colour. Once that's dry the remove what remains of the window mask then you are left with the detailing around the windows.

I use a very thin paintbrush, and the normal paint. Works just fine.
