Apart from immersing in hot water prior to fitting, any other tips? Start at the top of the toolbox and finish at the bottom? Use of soap or any such thing?

Well, firstly can I say a very big thank you for the numerous words of encouragement, tips, advice, explanations and good will in my endeavour to install a new toolbox rubber gasket.
Well, got the fecker fitted in the end with only one tear at one corner. My hands are as sore as feck. If I ever do one again (Please Lord, don't let it be soon), I will definitely radius those sharp corners before it goes for spraying.

there is a video on youtube - takes the guy about a minute....

Yes, John, watched it yesterday. It's UKoldschool from 7 years ago Doesn't even say whether he warmed the rubber in hot water before fitting it either

I always save old original ones and clean them up.
Nice and easy to fit

we were always taught at my "all boys" school, never to re-use an old rubber........................
