Discolouration continued
I have unsightly discolouration caused by bathmate pumping (and various PE over the years). The most annoying thing about it is that it stops about an inch and half before the bottom of the shaft, so there is a blatant change in colour towards the bottom, completely white below that. In fact, where it ends, there is a even darker ring, making it even more obvious.
I have had some success with DMSO + Iodine, but it is still obvious. Please, any advice welcomed.
