hey @SSessence, sorry to join the party late I hadn't seen the post until now!
The calipers look really nice, good work. I did the gold G2 kit last winter (me and you have a very similar car and wheel combo). I think the bright colors really help our silvers car silver wheel combo.
I also agree with the brush for doing the project. Went with like a wide and narrow foam brush from craft store and made it sooooo much better. No lines, no bubbles, no nothing. Cheers to some nice looking wheel wells now
