Leaking boot hotspots.
 

So found about a 3" puddle in my boot, its rusted in my spare :thumbsdown:

Think its coming in from the boot lid as there is alot of water on the underneath. Got some exterior sealant was going to remove the lip spoiler and reseal it. How is it normally fixed on?

Also where are the other places prone to leaking, figured Ive got some sealant may way well use it all!

Rear Light seals have been know to go. My old ZR rep suffered horrifically before I changed them

When that used to happen in my old Rover, I drilled a hole in the floor. At least I never got any more puddles............................

Here's one I made earlier:)

I knocked the bung out of the spare wheel well, at least it stops the water filling the well.
The water on the underside of the boot lid is most likely condensation, another place they leak is the trim clips that attach the top edge of the bumper.
