If you're curious about it working, spray some white sealer on a piece of scrap on one side. The other side just 2k. Then paint it. That will give you an answer.
Greens are notoriously known for their inherent translucency and lack of coverage, whether auto or various art paint. Buy a cheaper line like Omni and the coverage is atrocious. Some other hues have translucent characteristis too.
