Query: Very dissatisfied

Ordered a can and received it and felt that it was not a full can and quite frankly, filthy. I chose not to return it, as it could be cleaned up and the product itself could not be tampered with. I notified Amazon who quickly responded and apologized, truly awesome! Amazon sent me a new can at no charge. I did receive the 2nd can, which was in much better shape, not perfect. Sadly, both of these cans are now in the garbage. They both worked briefly and then they would clog and then no aerosol. I shook the cans well before applying...no idea what caused it. A total waste of my money. I appreciate the way Amazon handled the whole things though.
