Unrolling rolled rear arches

[Bdevo3]

As per title. My cars rear arches have been rolled by some twonk of a previous owner who decided an evo needed stupid big wheel and a massive suspension drop. Any one have any tips or have had any experience reversing the process. Im paranoid of muck gathering and rotting the arches. no signs of any rust yet so it's time to get them treated.

Rolled arches are the devils work

I doubt they can be unrolled without damaging the paint, how about filling them with wax?
