if it's bare aluminum,
1. etch primer (phosphoric acid mixed with normal primer)
2. normal metal primer
3. paint with whatever you want. Assuming that's paint. Spunk might not give such a good finish.

Spunk gives a happy finish

Thanks TMB, can I get all this stuff from Wickes? This is my first real DIY project.

phosphoric acid might be a touch tricky
but you can probably buy it as pre-mixed etch primer or aluminium primer. Otherwise, a proper motor factors is your best bet, it's a standard process for painting Land Rover body panels.

You can manually etch aluminium but it's a right faff.
