Crazy stuff.
Just for future reference, when you search sites like that, you can see the results as you searched for them, though you can't link to them. You basically end up linking to the search page so you'd need to give people the criteria to search for.
To be fair I hate siliconing. My old man is a window fitter and can do it while doing other stuff and talking and taking sips of his tea and whatnot. I'm one of them who has their tongue out and uses masking tape and ends up with my face really close to it to see if I'm getting it perfect. Never got the nack of doing it freehand quickly - it always takes me ages to clean a slight mess up.
