I used an airless spray gun
Something like this?

Yes similar, I use an Earlex one which is 450w not 45w, and my one has the motor on the floor with a hose instead of the motor on top of the gun. When doing a whole car it can get quite heavy. But if you're doing just a roof or bonnet etc then it should be adequate for the job.

That is only good for painting a fence not a car, you need a proper spray gun with a compressor
