Oakley Oil Rig Project. Pt 2.

Ok, so my first attempt with the Oil Rig sunglasses has failed, miserably. The paint would not smooth out or sand down at all and i just had no luck with them...
The new plan is to bring them back to a matte or flat black. they are sitting in a bucket of solvent right now which hopefully will help. Here is what they looked like after they were painted

Just the arms, the bluish rectangle is painters tape over the Oil Rig logo

Just the rims, the color reminds me of... well... you know...

Here is the left arm, the Oil Rig logo is the original black, but there are 2 shades of sperm white on the side

This is what made me decide to go to black again, the detail is HORRIBLE!

It wont turn out perfect but I am hoping that I can get it like this:
