you have to max your metal dragon to evolve him.

you should not enhance evo spirits to max ever (unless you need their evolutions). thats a huge waste of money. depending on the rank (C+,B',B+ etc) you can level them to certian levels to maximize their gold efficiency to use as enhancing spirits. please see the 'experience' page on this wiki. it is roughly lvl 10-15 and anything beyond is wasting money/experience.

I typically sell my dupe/un-needed evos since, recently, a lot of the event spirits are cannibals that can take 10+million gold to get to S. it also helps with space in your index when you have 10+ copies of the same card and 100+ books to level them up after you evolve them.
