chaps can I suggest some science..
Like dissolves like – water does not dissolve oil as they are at opposite ends of the polarity spectrum.
Lighter fuel is an alkane – it will dissolve only non polar materials.
MEk is methyl ethyl ketone – it is a relatively polar molecule – it will dissolve polar compounds.
Acetone is also a ketone – but more readily available from the chemists as nail varnish remover.
The difference between acetone and MEK is CH2 – i.e. not very much in a chemical perspective.
Cellulose paint thinners is a mix of aromatic compounds and ethanol. – low to mid polarity.
Meths is is methylated alcohol – mid polarity.
If you sniff a marker pen and it smells of pear drops – it uses amyl acetate – an ester as solvent – moderately polar.
From a science experiment – working form polar to nonpolar would give you the best chance of dissolving the marker before the paint.
As meths and white spirit do not work – I would also try nail varnish remover – acetone as my next step.
If these do not work – the pen used may not have used the ester solvent system.
