I presume a metal roof?

If you get everything clean down to the original then I would think that Eternabond tape would be good, but it isn't really cheap.
I'm not so certain about trusting Eternabond tape to stick to plastic roofing cement though. The sun will heat up the plastic roofing cement. As the cement softens the Eternabond tape bond may not be so eternal.
Have you considered a self leveling pourable 2 part rubber type sealant? It isn't cheap, but it should fill in to address your ponding.
Other than that it is hard to get anything cheaper than plastic roofing cement. With regular inspection and touch-up it can do a good job.
