Also as Pwo said above .The body under the battery tray is a bad idea .It has this dimple that holds water, and if the car is not used ,then it will lie there for ever till it evaporates..There are drain holes to let water out .If you remove the battery tray to check it out ,paint body under it with wazoil .If you dont like the look of waxoil then an oily rag is as good , but, you will need to do this every year. Another point to check is the gutters both sides at the rear of the boot .If parked on a slope rain water will lie in the area just under the rear window.Mine looks a mess in here but rust protected with waxoil. I may have water drain hole locations if you dont have them.But for the saloon only.
