Those turned out nice. The beauty of plasti dip is you can change them without much worry. I do see where the guys are coming from in regards to them looking out of place though with the bumper being chrome.
Luckily the body color is black which helps. You should look at the thread "Project Olds Cool", Donovan gave the taillights on his '80 Olds a pretty cool treatment.
I recently did restored the taillights on my '87 which was a ton of work, but worth it IMO. All of my trim is blacked out including the bumpers, so here is a before/after of mine as well as installed.
