3. Allows thinner coats to be applied.
All the above make for "no orange peel" which is horrible to look at on something we look at very closely.
Spray cans ( good quality ones) are capable of excellent results.
A reasonable time in the hot water is advised!! Too long, or too hot and it may burst
( although I have never seen that happen ).
This was shown to me by an automotive panel beater/spray painter.

Wise warning!!
Back in about 1961 I worked in a laboratory and was testing the physical properties of aerosol cans for pharmaceutical use. One test involved placing the cans in a temperature controlled very hot waterbath.
A colleague removed one of the cans to apply a pressure gauge to the nozzle, but accidentally dropped the can.
The explosion was deafening, the base flew off the can and hit him in a very sensitive place. It was quite amusing to the others in the lab but the poor chap needed hospital attention.
