Followed by sanding, cleaning and primer.
Next I took it outside once again for primer.
At this point the helmet is good enough to proceed. There are still a few small minor imperfections, but they are hardly noticeable. I bought some dark gray Dupli-Color car paint, and gave the helmet a few coats.
The finish looks awesome! But it still needs a few extra coats.
I like this color so much I painted the insides as well.
I let it dry overnight before masking off the helmet for the areas to be painted blue. The next day the paint job was a bit uneven, especially on the dome of the helmet, so I gave it another coat and let it dry overnight once again.
Once it was fully dried, I applied some painter's tape to mask off parts of the helmet for the blue paint application.
Next, blue spray paint.
For the last step I glued the comfort foam back into the helmet.
