    Sharp wood chisel will take the worst of it off then a wire brush in a grinder for the rest

    @arther dailey beat me too it but - Is the 3m hard?
    Have you tried a hot air gun and a chisel?
    That's why I personally don't like the single pack 3M or Gravitex type stone-chips.

    However the up side is if it's hard you could overcoat it with 87A.
    The epoxies are brittle compared to factory stone chip and may crack if applier over them, also you will not get the corrosion resistance of the epoxy unless it is applied to the bare metal.
    It is an excellent barrier so you will get some benefit.

    If you are having a hard time removing the stone-chip it may be OK but you never know whats hiding under it and if it's gumming up a wire brush it isn't properly hard.
    If you do decide to apply 87 over the existing stone-chip clean all the grime of it, sand it well, clean it again and apply.

    3m do a 2 pack which is brilliant but hugely expensive.
    Wurth, sika and dinatrol all do one that stays softish I think.
    I've used the sika and it worked well, @RaceDiagnostics had excellent results with the dinatrol (I think)

    Try petrol, it’s softened the stuff I’ve removed and then just scrapes off. Not trying to remove it with the petrol, just gets it all soft.
