Been tootling along with a few little bits and pieces.
First, I found that the rear shelf was getting damp and a quick inspection revealed that there was a small split between the rear screen corner and the hood. The rest of the plastic screen was in decent nick, so I didn't want to replace it for something so minor. A few days later while rummaging in the fridge for beer, I came across some weird stuff that my wife had bought for repairing charging cables called Sugru. It's basically a mouldable coloured glue that is resistant to all sorts of stuff including water. So I thought what the hell and moulded some to the outside of the screen and then another blob on the inside ensuring that the two met in the middle. After a few hours it was dry but still flexible.
I did a few other spots where there were tiny tears in the hood (they don't leak because they are minuscule, but better sealed up than not).
It blends in very well and seems to have done the trick. I guess time will tell if it's a long-term fix!
Next, I had a go at the top front grill and gave it a paint with satin black. Looks much better now and just the larger bottom grill to do.
Finally, my lovely wife bought me some genuine MG floor mats to tart up the inside a bit. They cost a lot for two mats but are subtle, very thick and look the part with their embroidered badges;
Now I'm just waiting for Rob the welder to be free to quote me for a proper job on the sills before the next MOT. I'm not sure it'll pass with the hole by the front wheel. :-(
