Are you painting it? Or taking it somewhere?
Its an immense amount of work, especially if youve never done it before. A good paint job is 100% reliant on good prep work. Sub par prep can ruin any paint job.
If your doing it yourself just make sure you have all the tools and supplies youll need. Sanding blocks, sandpaper, prep spray, primer, sealer, D/A sanders, masks etc etc. Most importantly TAKE YOUR TIME. It is not something than can be done in a couple of hours. Make sure you have a weekend (at least) set aside to do it.
