Thanks for all your comments – all welcome and very useful – pleased to see Torsten/Peter that you have already done some similar things.
Being new to Morgans I find this site a brilliant source of info and exchange of ideas – but it always seems to make my ‘to do list’ get longer!
Anyway, a few things were knocked off the ‘to do list’ over the weekend – some may be of interest.
The large holes on the nearside inner wing – particularly near the alternator have now been ‘grommeted’. I made two grommets from 2 cm neoprene sheet (DaveW thanks for the ideas here) – you can see how it fits.

The neoprene was cut to shape and oversized by about 1 cm all way round and then slit around the centre of the edge using a sharp knife set to a depth of about 1cm.

This plugged the hole as a grommet and is held quite firmly in place. Now over-sprayed with Dinitrol 4941 to make it look neat.
I used 4941 from an aerosol - much less messy to apply than anticipated. I was going to build up a thicker layer to offer greater stone protection elsewhere under the wings (following previous comments about stone starbursts but pleased to find that the factory now appear to apply some wing protection over and to the rear of the front wheels.

As far as I can tell there is nothing on the wheel arch behind the rear wheels so I may build up a couple of layers of 4941 to provide additional protection. Apparently building up thickness in layers is possible with 4941 – anyone got experience of this?
I noticed that the live feed to the engine starter etc terminates by a ring terminal over a thread held by a nut. The nut and thread were not insulated – so fitted a cap over the nut to prevent an accidental short with a spanner. I did short a battery many years ago and it’s not pleasant… blew a whacking great spanner out of my hand and across the garage (luckily no damage to me).

I can see a lot of sense in comments about gaiters on the lower springs of the front suspension (not sure about the tops ones) – so fitted a home-made gaiter made from tough woven polyester shower screen/blind material and a couple of bits of Velcro. Velcro stuck and sewn on with a half a plastic plant label behind the hoop Velcro to provide some stiffening.


The shower screen/blind material is thin enough to sit around the whole spring right down to the king pin mounting ring and all held in place with a cable tie. Time will tell if this is robust enough.
The three fuse box cover securing thumb screws on the +4 have a spacer nut fitted (unsure why as there is nothing near the threaded end in the fuse box when screwed down). But the locating hole is still quite open and does not form a seal.

Even though unlikely to occur, any chance of water getting into the fuse/ECU box is best prevented (particularly through the one centre top), so I removed the spacer nut and replaced with a rubber washer (tap washer) which forms a much better seal.

If anyone does this - be careful not to use the washer and nut spacer together as the head of the forward thumb screw may touch the bonnet when closed.
As I make these small improvements the more I get familiar with the car and its pleasing to see how the factory has finished off things in general on the +4 (2014 build) – as an example

the finish under the dash – pretty good and neat.
