At last, there is now a galvanised version of this door available!
High quality Galvanised Aftermarket one piece rear door for 2002-2016 Defender models

This is pressed from zinc plated steel sheet, so is coated inside and out with zinc so will last a very long time indeed!
The finish is perfectly smooth so also ideal for painting. As with any galvanised item, you will need to wash over the door with Mordant solution / T wash which dulls the galv finish down, then you can go over with an epoxy primer and then your colour coats. The mordant solution / T wash ensures the paint sticks properly.

The photos on our listing are of the actual product we sell, we do not use generic photos.

This is for 2002-2016 Defender but can be retrofitted to earlier models .
The only unique parts needed to fit to the earlier Defender are the glass and rubber seal which holds the glass in as well as the door card. All the other parts such as hinges and handle, check strap etc all swap over.

We also sell the complete puma rear door as a complete kit in our other items.
