Yes you can. A more appropriate question might be will paint adhere over a powder coated surface? I would lightly sand the surface, wipe with a solvent, and apply one or two coats of a good quality paint (I would use an oil based paint, but others should work fine.)

What is back ionisation?
Electrons which have not attached themselves to powder particles also travel in the air stream and along the electrostatic field lines to the item being coated. This is because it is grounded. The unattached electrons are attracted to the component together with the powder particles where they build up because of the isolating layer of the already deposited powder particles. If too many charges with the same polarity are deposited on the workpiece, the electrostatic force between the individual particles becomes so strong, that they repell each other and get pushed away from the surface. This is called back ionisation. Back ionisation causes discharges within the powder coat itself and also makes it difficult to coat complex shapes. Additionally, back ionisation causes the powder coat to be uneven and when stoved, the finished surface looks like orange peel.
How do you remove oxidation from your metal patio furniture?
sand blast, then powder coat it
How do you calculate coverage of a thermosetting powder?
Calculate the surface area of the item to be powder coated. Then after finishing the production(Powder coating), find out as to how much powder is consumed and how many items are Powder coated. Then calculate the coverage in square inches per Kg of powder used as under:- Surface area of item in Square inches x Number of items Coated Powder used in Kg
Why is powder in a chemical reaction used instead of lumps?
Chemical reactions involving solids work on the surface of the solid. A fine powder has more surface area than big lumps.
What refers to the color of powder scraped off a mineral when it is rubbed against a hard rough surface?
The color of the powder left on the rough surface by a mineral is called its streak. The streak plate is a hard surface that helps to determine the different shades and characteristics of the minerals that is rubbed on it.
When powder coating with a home based system is it required to bake the component afterwards?
A true powder coat system consists of a powder which is evenly coated on the target component, then baked to melt the powedered plastic onto the surface. If it doesn't require baking, it isn't powder coat.
Can you paint over powder coating?
Yes you can. However you need to be prepare the initial powder film for optimum adhesion required by the paint. One of the common processes to prepare is to buff or sand paper the surface (the initial powder coated fim) and then use the paint. In term sof chemistry PVDF, PU etc are good options for paints over powder coatings. Deepak Creating a good profile for the paint to adhere to is essential. 80 grit sandpaper or scotchbrite will create a good surface for paint to adhere to.
Which has a larger surface area powder or lumps?
A powder has a larger surface area.
Will exterior acrylic paint work on your metal gate that has been powered coated?
Not directly onto powder coat. But it will work if you prime the powder coat.
Can you use a gas oven to powder coat?
You can use a gas oven to cure a powder coated part.
Can you power coat over bondo?
I think you mean "powder coat" which an electrostatic process, meaning that the metal object acts as an electrical terminal in the process. Based on this, I would say you can't powder coat over a metal item with bondo on it. The powder will not "stick" to the bondo, only to the metal.See http:/en.wikipedia.org/wiki/Powder_coating

You don't
What is the surface area of aluminum powder?
It varies depending on the particle size of the powder.
How do you remove oxidation from your metal patio furniture?
sand blast, then powder coat it
Why is aluminium powder flammable?
Aluminium reacts violently with oxygen (any aluminum surface will very rapidly be covered with AlO2 [aluminum oxide]. If you have a powder the surface area is large and the reaction when heated will be quick enough to generate flames. Steel wool will also burn!
What does it mean to coat in sugar?
To coat in sugar is to have a layer of sugar on the whole surface. It is normally a thin layer.
