And a top assembly tip: the wishbones need to be fitted in the position they will be in with the car under load, fitting and tightening the wishbone fulcrums before you put them in will cause excessive wear/shearing on the rubber bushes.

As Naki mentioned, I have just finished same job due to rust perforations in the crossbeam.
I cleaned everything up using steel brushes on angle grinder, gave it some phosphorus acid, washed, degreased, zink sprayed, POR15-painted and finally coated everything with spray wax Dinitrol 77B (if I remember correctly).
I used original bushes for wishbones and v-mounts and polybushes for ARB. New stub axles and one ball joint changed as well.

I'm gearing up to do front and rear subframes as my next Jag job. Normally I'd copy the manufacturer's finish to keep things looking "factory", however I don't want to do this job again soon and know I can improve on the durability lifetime Jag provided. I'm planning to use products from Corroless. These paints are used for offshore oil platforms. They offer products which will "kill" (very minor) rust left over from wire brushing/flap discs, and other products which are applied to chemically "clean" items (very thoroughly grit blasted or fresh acid treated steel). I will be following the instructions closely to avoid disappointment. The bushes will be OEM and I'm considering using BOGE shockers.

I think sub frames rot from the inside and that foam filling does't help
