Wow, looks like my previous post was Dec 2020 - hard to believe a year gone by in the meantime!
An update is well overdue, and it might not be much but here’s a little cosmetic upgrade – kudos and thanks to
@MFA Mo Faraz for his support and supplying the decals, in case of the hazard switch and the lights bezel he actually designed them for my 1979 Eleanor.
Overall, I’m delighted with the outcome as I noticed the worn decals while restoring the interior (
1979 450SL Interior and dashboard refresh) and they’ve been annoying me ever since – despite my sincerest attempts to repair them using a white marker which proved futile, of course

At any rate here’s some detail on the pre, in-progress and post state - to clarify I’ve no affiliation to Mo, I merely want to share my “happy experience” just in case there’s someone else out there with a similar OCD levels about their Merc baby
Here we go – those are the decals, I ordered 2x of each as I expected I’d need some for trial and error:
The first item I decided to tackle was the indicator switch, the “before” condition wasn’t terrible but wasn’t good enough either.

First the old icons need to be removed, and I used a couple of ear swabs dipped in brake fluid – no going back after that! To my surprise, the installation was actually straightforward though you do need to be patient and have a steady hand – once the decals stick that’s it, there’s no opportunity to correct the position without destroying them… Which I learnt the hard way later.

After some consideration I decided to leave the wiper icon next to gear indicators as is – the originals were intact and matched the new decals just fine to my untrained eye.

I then used the backing paper and a soft pencil to gently burnish the decal.

Next one up was the hazard switch – same as the light switch, the icon was worn which I somewhat corrected with the marker but it annoyed me every time I looked at it
The scary moment of wiping the decal off – the point of no return!
The challenge was that one of the two decals got damaged in transit so, like a minesweeper, I only had one chance to get it right – and to my surprise I did!
Last but not least was the light bezel which would prove most challenging due to the location and shape – the point being is that I couldn’t apply the whole set in one go, instead I had to go one decal at a time. Alternative solution would be to remove the switch, though I’m not sure if it would have made a whole lot of difference.
I applied each decal separately, but I wasn’t happy as one of the arrows was off - and since I had a spare set I decided to remove it and get it right. That’s where things went wrong for me as one of the arrows from the spare set fell of and I messed up the second one - luckily Mo came to my rescue and supplied me with a spare arrow which I was able to install just fine; third time’s the charm!

Finally, to protect the decals long term some clear coat is required – I used Rustoleom which worked just fine. This step is mandatory as without clear coat the decals will get easily damaged, which defeats the purpose of the whole exercise.
