Gawd... Dude, seriously, were you cursed when you were in your mum's womb or something? :lol:
I'm sorry if I'm stating the obvious now, but the essentials for siliconing:
1 roll of TP to clean your hands and tool with (no, not yer wang, in this case anyways)
1 water spray filled with 1/3 water and 2/3 fairy liquid (stirred, not shaken)
1 small bin for dumping excess silicone into
1 excess removal tool (if you've got nowt better, a (removed) spoon works...)
Spray the silicone after you've applied it, and spray your excess removal tool. Becoz it's you, spray your hands too. And you face, and your hair, and your ***, just to be safe. Now, nothing will go where it's not supposed to be
