Best results will be using 2k bassed paints .BUT you will require PUKA breathing gear which means a big compesor to surply you with air aswell as the
gun....
Good results can be had with celulose....But is a bit more work...
The key to any sprayjob is the prep work.The more time spent here the beter the finish..and the second tip is patiants ,getting to much paint on to
soon means a large sagey mess

Its all about the six Ps.
Proper preperation prevents wee poor paintwork.

Cellulose will do you fine!
Preparation and a dust free environment to spray in are the most important things.
Practice on some panels hung vertically until you can get a good flow without runs. Optimum being as little on but still flows out before runs or
sagging! It is a fine balance between too little and too much. Too little looks dry and powdery after you have sprayed it. Too much looks very wet and
can run or sag.
Most people think that practice means just one item. It means as many as it takes to get right repeatedly! One lucky pass will not teach you anything.
If you think you got it right try another with slightly more paint on and watch the effect as it dries.
A dark colour would be good for practicing with as it shows defects better.
If you are going to do it in a garage then get the preparation done first then clean out the garage. Line the walls with sheets of plastic if you can,
it stops the dust from entering spray area.
When ready to paint wet the garage floor, again to reduce dust.
Air temperature will affect how the paint dries. Too cool and it takes too long allowing dust and/or insects time to contaminate. Too warm and it will
flash off too quick, affecting the finish. Also if it is very damp outside you can get blooming. The paint goes cloudy on the panel.
Lastly good luck and enjoy it!
Cellulose is the easiest of materials to paint with. If it goes wrong just let it dry thoroughly, flat it down and try again over the top. No need to
re prime unless you go back to base metal or surface.

In answer to your primary questions, my best suggestion would be to go to the shop where you intend to buy the paint from and chat with them about it.
They know best about their products (or should do).
1. Prepare the surface ready for paint, making sure everything is as smooth as possible. Lots and lots of rubbing down. This is the hardest part of
any respray.
2. Etch prime any bare metal then prime all over with a high build primer.
3. Flat it all down again untill it is perfectly smooth. The paint will emphasise any defects not hide them.
4. Paint it with colour coat of choice and then laquer if neccessary.

Practice on some panels hung vertically
The back of the shed door Holding the gun too far away or too close and moving too fast or slow affects the finish. I don't paint that often
these days but I found that using too fast a thinner affected what I did as well. If the wet edge dries too quick you get the powdery look between
strokes and it looks like a tartan. Sod's Law dictates that any bits you don't see or aren't bothered about will always look
brilliant, like underneath a bonnet and don't worry too much about the insects. Let it dry before you try to remove them and you only get the
feet

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Flick around the edges of the panel before you make the main passes - the edges always need a bit more build.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Make sure the gun dosen't drip round the cup seal !!!
Nothing worse than painting a flat panel then getting drip right in the middle.
