stainless trim retainers

I have removed all the trim without bending, except one piece that has a slight arc.I think it will go back on without any prob,s. it,s amazing how much junk was behind the stainless.I now have rust stripes every where there was a retainer,the retainers were pretty degraded.I can save a couple of pieces of retainer but I'll need something to reinstall trim after paint. Has anybody used clips or retainers from R,J and L or Restoration Specialties and if so what part numbers worked well. thanks in advance J.R.
