I had my mind set on overlays but changed my mind at the last minute. Yesterday I decided to just paint my tail lights because I hated the clear anyways and wanted the change to be permanent. Went to Autozone and picked up Duplicolor Metalcast red and some clear coat. IMO the biggest pain in the ass was getting the hatch liner off and putting it back together, it didn't line up very well. Just took my time masking the reverse and blinker lights but even that wasn't to bad.
Ended up putting about 3 thick coats of Metalcast then wet sanded it with 2000 grit (helped smooth the paint out great) then proceeded with another 3 coats of clear coat. here's the finish product sorry about the size:
