The phase 2 liners are complete, as in they line the whole arch.
The rust issues inside the rear arches tend to be limited to surface rust, unless the car's had a very hard life in 2 feet of saltwater.... The main rust issues with the Phase 2 are the chassis legs at the front edge of the floor pan and then up behind and around the bump stop and the funny little box sections at either edge of the boot floor, or where ever they have been wrongly trolley jacked...ask me how I know....
