1980's 123 series Clear Coat problems

Short of a re-paint, is there anything that can be done about peeling clear coat? I understand that older 123's had clear coat applied over the paint at the factory. I understand that current paint practice is to mix clear coat with the paint color which supposedly eliminates the peeling problem.

It would be nice if a ....rattle can...solution of clear coat could be applied. Does anyone have experience with this? Any other ideas as to how to fix this problem?

560sel ignition coil

Have a 1990 560sel with 127k miles. Want to start changing the oil myself via the dipstick. Other sites say that it's best to disconnect the ignition coil before cranking the engine over after the change. This prevents too much strain on the timing chain. Have a repair CD but the coil is not behind the EZL as shown on the diagram. Looking for the location of the coil. Thanks.

Bosch Duratherm for a 1980 240D

I bought a Bosch Duratherm glowplug upgrade kit off of Fleabay since Kent was out(same as this one : https://mercedessource.com/node/691)

At any rate, I get the box and on the side it says W123D 08.80- which
to me means from August 1980 on. Well my 240D was born in March
1980. I do have my 1982 parts car in the garage and it does have a
different glow-plug set-up than my 1980.

I could cannibalize the parts car glow-plug setup and transfer it
over to the 1980 recipient car as it will eventually get the 1982 motor
as well.

my 83 turbo diesel stalls after about 25 miles l

I have an 85 300 CD with an 83 engine, my problem is that after about 25 miles the engine starts slowing down and then stalls like it runs out of fuel. let it sit 10 minutes or so and it will start again and run fine for another 25 miles and do the same thing again. will run all day at an idle it only does it at highway speeds. Anyone know what is causing this?

thanks for the help

Air Dam removal

I have a 79' 240D and have been doing the maintenance on the sun roof as per the Mercedessource kit. I have found that the air dam has a bit of rust on it and I wanted to remove it and clean/treat it with the anti-rust paint but I am unsure as to the best way to remove this. I am afraid of breaking it if I force it. Does anyone have any sequence of steps used to properly remove the air dam??? Thanks.
