As a matter of clarification, Rey and his 15 year old MP5K are in the Philippines. The buffer is turning soft and I'm not sure whether its a reaction to the unnamed solvents, lubricants. Through a relative, he's getting a replacement part here in the US. He described it as pliable as butter and I take it that the polymer has reached the equivalent of its phase transition point. Any suggestions or polymer engineers out there?
