aerosol paint, and spots
Discussion
Hi, i had a small area that needed painting, bought a can, it's still half full of paint but the pressurised air has run ran out, how blardy annoying.
Also there is some areas where it didn't cover ie, small 1mm spots of underneath colour showed through, could this be that i didn't clean it properly.
Any help thanks.

Sounds like you didn't shake the can for long enough.
You really have to go some for a couple of minutes at least before using it. I think that part of your problem may be grease/silicone on the panel, but more likely the solvent has gone on there without enough paint on it due to the lack of a mix.
Seriously, you need to mix the solvent and propellant with the paint. Shaking the can for a minute or so will not achieve that.

It is the most common thing that people do with aerosols.

"At one time or another, everyone one has used an aerosol can of some type. It is simple and anyone can use them. You just point the can, press the spray nozzle and that’s it. Even though it seems very simple, there are important instructions and safety precautions that need to be followed. These are printed on the labels of each aerosol spray paint can. They include instructions about shaking the can, when and where to use the product. Even how to properly clear the spray nozzle after each use. That will ensure that the next time you need to use the can, it will be ready. Certain steps should always be taken, every time you use an aerosol spray paint.
The first and the last things that you do, when using an aerosol spray paint are the most important. The first step is always to shake the can vigorously, and listen for the shaker ball to rattle. Then continue to shake the can for at least one to three minutes. This helps to assure that the paint is thoroughly mixed with the solvents and propellant that are also enclosed in the can.
When the color of the paint varies from the expected color, the most common solution to this problem is to vigorously shake the can. Since the propellant used in aerosols is a liquid gas, the propellant mixes with and actually becomes part of the paint. The pressure of the propellant as it escapes through the opening of the spray nozzle, allows the paint mixture to propel out of the aerosol can. Thus another important reason for shaking the can. During use, the can should be occasionally shaken to insure that the paint stays thoroughly mixed at all times. The pigments of the paint can settle to the bottom of the can, while spraying for a long period of time.
To insure that the aerosol spray paint works every time it is used and the contents of the container are completely emptied out. The last thing you must do, is to clear the spray nozzle. When you are finished using the aerosol spray paint, you must turn the can upside down and press the spray nozzle. This removes the paint that was left in the spray nozzle and the dip tube. Immediately after the paint has been cleared from the spray nozzle and dip tube, the color of the spray will become clear. At that point, the spray nozzle has been adequately cleared of paint. You can now replace the cap and store as recommended on the can label. The aerosol spray paint will be ready for the next time you need it. When using aerosol spray paint, these two very simple, but very important steps must be taken to achieve maximum results.
So if you follow these simple and important instructions, when using aerosol spray paints, you will help ensure that the color of the paint stays uniform with the original color. You will be able to completely empty the paint from the cans and get the maximum coverage that you deserve. Using aerosol spray paints are economical, easy to use and produce professional results."
