I have noticed a small amount of surface rust on the roof of my white Series IV. Looks like something has rubbed there in the past.
Does anyone have a guide on a quick touch up with spray cans? Being on the roof i'm not worried about the looks.
Ive just fixed a 3mm hole on my roof gutter (temporary) as a spot weld had let go and rust started.
I sanded it back with a dremel, , used some rust converter, primed it, used some sika 291, then some touch up paint. This all up is 10mm wide.
My rust will return as i'm sure its inside. But this is a temp fix before I have to take it to a panel shop. But if yours is just surface rust , follow the same steps (without sika) and you will be fine.
