go to a auto paint shop. Best is to chat to the dude at the place and tell him what you are doing because i know, we in South Africa use a different naming scheme for the paint side of things.
Bottom line, you need an etch primer, ask for a anti corrosive one.
Then you need paint, it comes in tins, 500ml, 1l, 5l etc. You will probably only need 1l of silver.
If you get a 2K silver, you will need harderner. Ask for FAST harderner, anything less will take forever to dry unless you bake it.
You will also need 2K thinners to dilute the paint before spraying. You cant use normal thinners, it has to be 2K thinners for 2K paint, you will notice it smells different to normal thinners.
You need a decent gravity fed spray gun and a decent compressor to drive it.
Like I said, go to a auto paint/customs shop and they will/should give you the detailed info you need about how thin the paint should be.
One thing to remem,ber is once you have added hardner, you HAVE to use the paint, or at least dont leave it in the gun. It will congeal.
