Replying to Tips for ski waxing?

Alright so I just coated my skis in wax and I'm waiting for them to dry so that I can scrape it off.

BUT I'm sure some of you will know better ways of waxing skis than me and can probably give me some tips, as in:

How long should I let the wax soak in for?

Is it important that I iron the wax along the length of the ski, or does that make no difference?

When I scrape it off then brush it, how much do I need to get off?

Thanks!

Oh and please don't tell me which type of wax to get, I live in Austria so I probably can't get the same type as you :)
