I've got a Karmann Ghia that I need to print on my FDM printer and from what I've printed so far know I will need to do some putty work.
The parts on the end were printed with the standard nozzle, but the middle piece was printed with a smaller 0.2 mm nozzle I bought later.
The .2 nozzle takes a bit longer but as you can see, the detail is much better.
