Well, not in the cave but on the boat. Varnished the floors, bulkheads and seats, then accidentally kicked over the can and poured half a litre of the stuff on the carpeted, sloping, cockpit floor. Said some rude words, tried to mop it up, then leaned my arm on the freshly painted seat, said more words, and grabbed the support behind me which was also wet. Then I gave up and I will assess the damage tomorrow. Can't even think who to blame.
