Ok all you Pro spray painters! Powder coated pool fence needs to have a colour change?

We are renovating a pool area and we would like to change the colour of the pool fence. One would imagine that the steel fencing is powder coated ';about 10 years old'; and has some oxidation starting to form. Can anyone tell me if I need to use some type of solvent first to remove the oxidation then maybe I need an etch primer or something. If someone has had this done before or does it for a living? any info would be appreciated. Cheers Marty Down UnderOk all you Pro spray painters!

Wipe it down with a product called ';ospho'; then paint it with a good exterior oil based paint..If you use a latex paint you would have to then prime it anyway with an opil based paint..and then the finish coat..with ospho this product also turns any rust on it into a paintable surface..according to your question you are in oz..and I do not know the availability of ospho there..but there is also a brand of a product that is the identical product to ospho, and it is under the ';jasco'; brand name..here is some info on these products..I am a 37 year experienced painter..and wipe all my metal repaints down with these products..pay no attention tothe prices here..this is a bulk price per case..
