Started with removing the rear step and wheel carrier.
Surprising how ‘good’ the paint was where it was covered from the elements. Weirdly the right crossmember through mount was far more corroded than the left and the general condition of the step, after 7 years was a surprise. Please ignore the flaky hinges and dented safari door  They’re on the ’to do list’...

Got on with prepping and painting the crossmember and seeing as though it was off, also attacked the spare carrier. 2 coats primer and 3 satin, decided against using gravel guard, preferring a smooth finish. Brush painted the carrier with a rust converter and primer, sprayed with same satin black. The rust in the tubes for the wheel  , why are they left open

Sprayed the fixings for the step with gravel guard.

First tried pouring a galvanising stripper and cleaner into the threads, but after a full day it had only removed less than a mm, but did removed all the powder. Luckily could start a tap into the threads. 2 turns of the tap, remove, chisel out galvanising, tap 2 turns, repeat, repeat, repeat & 4 hours later, done! I sprayed the inside of the step with Tectyl 506 and plugged all the holes with a mastic rubber. Click image to enlarge Click image to enlarge Click image to enlarge Eventually all back together. All fixing were coated with ACF50 and inside of crossmember with Tectyl. Did not expect the powder coating on the step to be so shiny, the sample in the shop was more matt, sure it will fade in time. The open end of the tubes on the carrier were plugged with 22mm table leg rubbers and sealed with silicone. Used the same rubbers, less silicone, to seal the inside of the step jacking points, still have the originals on the outside. OCD kicked in and painted the washers and bolts with model paint enamel (have a tin for keeping the rivets on the chequered plate black).

Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so. Douglas Adams 2012 2.2 Puma |

Thought I'd add to this thread rather than starting a new one...
When I first got my 90 I 'made good' and resprayed the rear end noticing at the time that the metal plate under the rubber tread on my OEM LR NAS Rear Step was shall we say a little on the mean side being 'waffer thin'...

Click image to enlarge Questions... Who has done what to correct this... 
I seem to remember seeing a Aluminium Tread Plate alternative being applied to improve things...
I would like to retain the original appearance but would deviate from this for a good solution...
Thanks for any suggestions... SKIP https://www.defender2.net/forum/topic83242.html |
