If you just want to remove remaining paint Billy ...(and re-paint) I suspect it would VERY soon (especially as you say it's faking already!) rub off with some 180 or 220 grade wet and dry paper.
Use it wet,with a little Fairy liquid and it'll cut better,and keep the dust down
That will also help will key it up....for some etch (aerosole) Primer,which you can get at an automotive supplies along with some two/pack car paint....which you can also get mixed up at the same place in you're choice of colour?..Matt or Gloss ect...Mask out and use dust sheets and apply with thin coats,till the right finish is achieved
Best option IMO if you're not going P.C.
