Note: the batarang model is made as a push pin model that sticks to a bulletin board with a short side (the left side).
When the batarang is stuck to a bulletin board it would look like it was sticking into it as though thrown at the bulletin board.
Testors Enamel Paints - 10 pack of small model paints for about $12 from blick on Market and 6th in SF
Paint brush (as included in testors kit)
3D Model to paint
disclaimer: I realize that the actual batarang is all black and this painting was done for a learning experience rather than an attempt to exactly duplicate the original.
I made it at Techshop http://techshop.ws with a Type A Machines Series 1 3D Printer

Step 1: Initial Coat - Painting in 3 Areas to Compare Multiple Coats
1) right side
2) left side
3) middle area
The initial single coats of paint will be compared as I put additional coats on the right side and middle painted areas.
When painting the first layer it went down pretty well and offered about 40-60% coverage.
TIP: When painting on a 3D printed model you are likely to still be able to see the individual strands that make up the PLA print even after a single coat of enamel was used to paint over the print texture.
Step 2: Close Up - Right Side of Second Layer of Enamel Paint
The second paint layer provided about 80% coverage in terms of not being able to see the black color below the painted area.
TIP: A second coat is a requirement for a good quality paint job on top of PLA.
In the additional images you can see the "shorter" left side with only 1 layer of paint has less coverage and shows some of the black layer underneath.
Step 3: 2 Coats Over 60% of Surface
When printing with enamel paint from Testors ( http://www.testors.com/category/135894/Enamel_Paints ) follow some basic safety precautions with fumes from both the paint and the paint thinner included in the set for cleaning your brush.
TIP: Be aware when painting and make sure to work in a ventilated area - (seriously ventilation is required).
Step 4: Painting a Smooth Surface or a Lumpy Surface
NOTE: There was a slight difference in the amount of paint used on the first layer compared to the second layers. This was possibly a result of paint filling the spaces in between PLA strands on the model.
TIP: When painting onto PLA printed models make sure to apply thin coats of enamel paint.
Step 5: Painting in Black on a Black PLA 3D Printed Model
Shine: The enamel in both the red and black areas provides a shine that is more brilliant than the unpainted section
TIP: Expect that 2-3 layers will be required to provide good coverage on top of PLA printed 3D models.
