Ok, i just went and got a old rim and rubbed some tar on it.
Then on one side i rubed it with Meff and on side Linx (Y)
Results:
Meff - tar came of easy but as you said dan , leaves a greasy surface.
Deodrant - Same again very easy to rub off , but doesnt leave it all greasy.
i also found it is easier to rub off old tar on a rim, when i freshly rubed it on it was much harder to clean off.
so deodrant i would say is defintly better.
