Try any auto paint supply. Not familiar with Brandon but in Tampa there is Auto Body Express on Florida and Fowler I believe or Finishmasters is all over, or NAPA I think still has Martin Senoir paint. Maybe a local shop will sell you a few ounces if you promise not to drink it or something dumb like that.

By the way the "drinking it" part is not a presosnal attack. Shops are just scared of chemicals in the wrong hands.
