If the mini Pf were mine id be cleaning her up.
Heres what i would do.
A VERY light sand
Clean up with meths and ME - same as you would ball swirl to remove most of the dirt from the cracks.
Then a very light colour wash on each of the colours... this is a very thinned out wash of paint.. it makes all the imperfections disappear and will colour the planking cracks. I normally do this with a very soft sable brush thats not dripping but its not dry either... it leaves no brush marks
Then a CC.
PF will look like new again
