The tailgate latch started to go rotten on the golf and I left it a bit too long to fix...

result is the tailgate paint has blown around the handle now....

Result was a trip to Essex for a replacement tailgate. Came off a 52 plate V5, got it for £50 with a factory spoiler

The handle on this one was beyond salvation and tailgate required a little paint repair under the handle.
Today I handed my life savings over to VW for a new handle 1J6 827 565 B (GRU) Needs paint.
I'm considering changing the boot over this weekend.....
Do I go for the bolts under the headlining and have to reseal the brackets?
or
Source an 8mm female XZN and tackle the wierd ass bolts on the tailgate brackets?
One last thing, anything I can apply or do to the handle and lock to stop the rot again?
Thanks!
