To add few more things.
Peter.
Smallish air comp can be bought for $150. spray guns another $50. try go for 1.3-1.5mm nozzle.
for $200 outlay your job will be easier and better. Air comp are always handy and the small ones are easy to store away.
I got a small 2.5hp air 25L comp paid $99 for from Bunnings. use it for small jobs. though i do have a large industrial air comp with quite expensive spray guns for my bigger jobs.
Even with small compressor you cannot do a complete car at once but individual panels are possible. Ones with 40l tanks are ideal even for bigger jobs. noisy buggers but work reasonably well.
if painting 2pk stuff (i'm kinda sick of OHS relation with 2pk, im pretty sure everyone knows how bad it is so as all the other paints) so a suitable mask is required for any spray job be it acrylic, enamel or 2pk.
You cannot get it from bunnings or repco and like.
Have to go to specialised crash shops. cost of mask from $200 to 2k for full face oxygen masks for 2pk applications.
Alternatively go to a crash shop ask what they have and use and info where they get it from.
There are some paints you can get that are still 2pk with reduced harmfull crap. cost bit more but its an alternative. though i haven't seen primer filler version of this.
spray cans are good for small jobs like toys, bikes, signs etc..... cost per liter the spray cans are a lot more exy than buying a cheap air compressor and spray gun.
have fun.........
