Mould - best white silicone to use?

[Mk5 GTian]

I have been installing bathrooms and tiling for thirty years ,   The only thing that works is Everbuild FOREVERWHITE, it stays brilliant white for years ,a stunning pruduct!!

I'm a decorator, and only ever use Everbuild Caulk. Great stuff that actually moves with expanding and contracting wood, rather than just splitting. Can be used inside or out. And it's 1.50 a tube! Brilliant.
