Removing gutter rust?

[Kempy]

Whats the best ways and means of stripping, repairing and retouching rust that forms in vehicle roof gutters?

It starting to show in my 70 series and it is something I would like to address properly. There is a rubberised coating in parts of the gutter that I need to figure out how to remove aswell.

Help appreciated,
Kempy.

is it pitted/flakey rust or just surface rust? grind it back,grind/scrape out the sealer.brush rust converter on whats left,prime,re-seal and paint.POR15 is the best rust converter/paint on the market but at $80L bit dear.May be cheaper to get a panelbeater/painter to do it.

There are various bits of rust that have formed. Most of it is just surface though. Ill give it a go with the stuff Ive got and see how it pans out.
