Stripping and Painting Metal Windows

[sibruv]

Hi Guys, first time posting, wonder if anyone can help me.

I have some old metal crittal windows, and the paint has seen better days, flaking etc, whats the best way to a) strip these, and b) repaint them ? I was going to get some Nitromors, as I dont want to muck around.

if Nitromors works, can someone tell me how I go about painting these Metal Windows properly ? can I just use a non drip gloss ?

Many thanks

Simon
