I'm not totally happy with the paint. It seems to be my luck in life. I end up painting everything twice or more. But right now them might the 6 foot rule. They look pretty good 6 feet away or farther.
Speaking of center vents. I received some aluminum center vents from a run Bob did and got them today in the mail. Very nice! I'll need to figure out how to put them together and install 1 set in R5. The other is a backup incase I want to paint them black and put in Q5.
I'm also painting my other horseshoe today so that will be ready to mount on Saturday.
