Danger bhai bake paint is no rocket science, the car is put in a paint booth which has vacuum vents in the floor and the roof to control humidity and booth is sealed to prevent dust from entering during the painting process.
After the paint has been applied, the painter exits the booth and now the baking process starts. Hot air is pumped into the sealed booth till reaches a desired temperature, and then this heat is maintained to ensure that the paint dries, this process is called baking, hence the term bake paint.
Once the vehicle is "baked" it can leave the booth, the baking process is quite short, usually around a couple of hours.
If all the plastic trim (mouldings, dash board, door handles, bumpers etc) are not removed, the baking temperature is kept relatively lower to prevent these trims from de-shaping.
In Pakistan the bake paint booths are usually not operated on the max heat range, however it is still more desirable to use a booth as dust will not settle on the paint surface while the paint dries and humidity is also kept out.
You havent posted pics of your Prado, really need to show the condition of the paint if you want to receive more comprehensive advice.
