If you are going to all the effort to paint the calipers, it's much more professional to get a stencil to paint the logo as well. I just did that on some other brakes, and I had my local print shop cut the logo stencils for me out of adhesive vinyl. It's easy to find the logo graphics online and size it exactly how you want. Sometimes people sell stencils on eBay too, but I haven't checked for Tesla.
