LOL, dont wetsand to METAL... haha
I actually just finished doing my whole car with aircraft stripper, it will take you abotu 60hrs taking your time, so be prepared.
I am not a big fan of stripping with sand paper, chemical stripper, really you need 2 gallons, its like a 50-60 dollar job for the whole car, be carefull witht he type of primer you use if you plan on DDing it, for corrosion protection, I would go with a etch prime of course, and then a epoxy primer/sealer on top of that.
Good luck.
