General tips needed for my first spray job!:-)

[rumpelstiltskin]

Well,first spray job on a whole car apart from painting my buddies car with a bin liner full of empty cans to show for it!:-)Anyway,im painting my Renault 5 Lecar Turbo.What's lying in front of me is a car with original paint,new wings and bonnet,fillered repairs etc.What i intend to do is cover the whole car after i've keyed all of the surfaces with the 2k primer i've got from my local paint store.My thinking is to cover the lot,flat it all down so all the panels are singing off the same hymn sheet,if you get my drift.Is this ok to do?I've keyed original paint etc with 320 grit wet and dry,also the other panels too.The colour im painting the car is just a celly white.I've got 5 litres of the stuff and thinners obviously.Anyone got some good general advice to give me to help me through this,im bricking it lol.Maybe even what's a good spray pressure for the gun etc?Gun is by Airgunsa,cost about 50,60 quid.Got a SIP 150 litre 3hp compressor,moisture traps for the line,good mask too for the 2K etc.

Make sure the compressor is drawing in air from outside the spray area & wear an air-fed spray mask. 2k uses cyanide compounds as an activator.
Did you say you are going to spray cellulose top coat over 2pack primer?

Sorry my mistake,not celly(That's the original paint)do you get 1k paint?It's a white gloss paint they have given me,doesn't need lacquer?How do you get air to go into a compressor from outside?I thought it just sits there and pumps out air lol.

Yes, you can get single pack (1K)that doesent need hardener, but TBH, its pretty poor quality stuff. Direct gloss (solid colour) doesnt need a lacquer, it probably will however, need a hardener.
Ask whoever sold you the paints for the data sheets, these will tell you the gun set-up, spray pressure, mixing ratio (including thinners [if needed] and hardener mix), flash-off times & curing times.

It doesnt "make" air, it merely compresses it (see how they thought up the name?!) and then pumps it to the gun/mask!
If you have the compressor in the same area as you are spraying, it will be drawing in paint fumes. Even if you have in-line seperators/filters and an air-fed mask (which is fed by the compressor!) you will still be exposed to the paint fumes. Make sure the compressor is in a seperate room, or if its a dry day, outside.
