Still kooks good to me GK.
When it is so cold it is hard to get a high gloss, even with the best paints.
One thing you could do to help get better resultes, is to put your small items in the oven on low, basicly just turned on.
Don't try and speed up the proccess by over heating the item to be painted, this will just burn the paint and will look crap.
By doing this it will take the chill out of the steel/aluminium. Have everything ready to go outside where your painting.
That way you can paint as soon as you hang up the item your painting (coat hangers work really well for stands to hang/rest thing on plus there portable).
By the time you get outside the item will be about 25-30c degrees.
Once you have painted it, bring the item back inside to dry fully.

Keep up the good work mate.
