Solve the leaking Boot problem.
Helpful insights I discovered with the same issue.
1) Check and re-seal the rear tail light surrounds, often they come loose over the years.
2) Check your Radio Antennae is sealed above the battery location for a dripping leak.
3) Check the metal latches above the boot are tight and the seals below them are in working order. (Phillips head only required)
4) Check your drain holes, behind your soft-top, in the corners behind the seats are 2 small drain holes, that often get full of mud and debris over the years, to access this location, un-zip your window and lower it, while leaving your soft-top up. Put your hand in the corners behind the soft-top anchor points and feel for the hole. To clean, either put boiling water down the hole, or use a compressed air gun, or both.
5) Your rain rail that guides water from the parcel area, could be broken. Expensive to fix, but a replacement part I am told is "invincible" maybe a new compound of product with the old design. Worth the investment if the above don't solve the issue.
Anyways, welcome to the community.
Nice choice on the NA8
