I have done and redone rockers on 6 cars in 34 years.
You did not say if they were metal, and I have no familiarity with the raised letter versions. Are they metal?
So, if metal, here is heaven in a sentence, or 7.
Satin black powdercoat cost 50 bucks. Peel them off and check the jackpoints, then get the kits from AA.
If the jackpoints are rotten, cut them out and buy new tubes and plates from Restoration Design in Canada. 70 bucks for both sides.
See the picture below of mine cut out before and after welding. You must check the jacktubes. Or there will be blood.
Then, if metal, just take them to powdercoaters, but if there is rust, you must weld the holes closed in the metal rockers. Powdercoating melts Bondo.
You will have a hole where Bondo was. Sort of nothing short of powdercoating looks like it was factory.
Then, when you get them home, you can mask and paint the PORSCHE if you must.
I like them black on black. If your's are metal, powdercoat. Otherwise, rattlecan away.
