Nitro methane will remove it.
Lacquer thinner, acetone etc will not soften or remove it.
Interesting stuff ...
Wiki says
The principal use of nitromethane is as a stabilizer for chlorinated solvents, which are used in dry cleaning, semiconductor processing, and degreasing. It is also used most effectively as a solvent or dissolving agent for acrylate monomers, such as cyanoacrylates (more commonly known as "super-glues"). It is also used as a fuel in some forms of racing. It can be used as an explosive, when gelled with several percent of gelling agent. This type of mixture is called PLX. Other mixtures include ANNM and ANNMAl – explosive mixtures of ammonium nitrate, nitromethane and aluminium powder.
As an organic solvent, it is considered to be highly polar (εr = 36 at 20 °C and μ = 3.5 Debye) but is aprotic and possesses very low Lewis basicity. Thus, it is a rare example of a polar solvent that is also weakly coordinating. This makes it useful for dissolving positively charged, strongly electrophilic species. However, its relatively high acidity and explosive properties (see below) limit its applications.

Maybe it aint the safest of stuff to be playing with in the onfines of a car or unventialed garage as the wiki lists lethal dose levels of less than 1g/kg of body weight. So caution is required so don't get it on your hands or breath in the vapours would be a good suggestion
