Doc here,
If you can get some, and you have no rubber / Plastic parts...
Methyl ~ Ethyl ~ Keytone (MEK) will remove ANYTHING..
Be careful with it, wear gloves, Goggles and a respirator..that Stuff can kill you..now and later.
Do it outside with good ventilation, and Do not spill it on your driveway..It will MELT asphalt.
