what to you guys think? it's a cheap ripoff of anodising i guess.

No way! Do not run paint through the radiator. I work at a radiator shop and we build rads all day long. First off, the paint will plug up the tiny tubes running through the core. (99.9% sure of it). Second of all, you don't need to insolate the inside of the radiator to keep it from galvanic corrosion. Use distilled water, an anti-algae additive and a little bit of Anti-freeze.
Chemists developed anti-freeze for cars to prevent the coolant from freezing. What people don't know is that they also developed it to lubricate the system.
When you touch straight anti-freeze with your fingers it feels oily. It doesn't feel like water.
Another thing is if your system is corroding up fast, (white gunk through the system) You may have an electrolis problem. Cars have this problem too, because water is an electrical conductor so you have to keep it grounded.
How electrical current is moving through your system is beyond me, (maybe through the pump), but try putting a ground from your radiator to your case.
DON'T put paint through the inside of your radiator. You'll kick yourself in the ass for doing it.
