Ethol lpd replenishment?

[weasel]

I am getting ready to mix a can of ethol lpd. On the can it refers to a replenishment scheme, but they ask you to write them for a technical bulletin. Their website does not have the info. I did a google, but could not find the specifics as to how one does this, only that you can.
Can any body tell me how you replenish this stuff?

LPD lasts so long I don't know why you'd want to relenish it. If you bottle it after every session, it will last so-o-o long you won't believe it.
