Use a chisel and a plastic mallet. Or an Exacto knife. However, if the Bozo bedded the barrel channel, the stock is toast. The stock will require cutting off and the remaining mess chiseled off.
Palm sanders are for finishing, not lump removal.
I'd be trying HiBC's paint remover. Probably before a chisel. Living better through chemistry. $10.24 per qt. at Home Depot.
Rumour has it that Circa 1867 paint remover works too.
