Take pictures and document it with the complex before you do anything. Also before doing anything take it to both a dealer and a professional detailer and get a written estimate to present to the complex.
I personally would have no problem trying some various compounds on it with an electric buffer as I have a fair amount of experience. But I would not touch it until you do the above so that they can't blame any of the damage on your efforts to get it our yourself. The first thing I would try is a clay bar. Then I always work my way up starting with mild polishes and progressively up to something a little more aggressive. At some point you have to know you limitations and let the pros work on it.
