Paintwork Touch-up

[Midas]

I've noticed some small spots of rust on the painted bodywork of my car, a 1992 Supersprint (around pop studs and some bolt holes). I have the top coat paint but am not sure whether I should use a particular undercoat and rust treatment. On 'normal' cars I have always used Jenolite rust eater followed by the standard primer and then top coat. I presume Ali bodied Caterhams are somewhat different - or are they?

 

Any wisdom on tackling small rust spots?

I'm no expert, but I doubt it's rust you're seeing - probably aluminium corrosion, v similar to rust, in that the more you dig the bigger the hole will appear - in fact it's a bit easier than rust - you don't have to put much effort into the digging!
