The main frustration with Plumbers Mate centers round how to manipulate it. Nobody doubts it works when applied correctly but it's just properly hard to use. If you've got to return a WC to a pre-existing dodgy-looking pan connector you've not the time or inclination (or available stock) to replace, a ring of plumbers mate round the WC spigot (properly cleaned with an abrasive pad and some wipes first - oh joy) will sort it every time.
The way I've found that works is to never handle the same mm of it for more than half a second at a time. Keep it moving from finger to finger or it will stick to you. When you've got it where you want it start proding it at a million miles an hour, really quick, soft, finger moments pressing and persuading it this way and that. It starts to mould to your will rather than act like an autonomous little beggar. Bit like the wife.
