as the title asks,

does anyone have a favourite rust stopper. Im looking at treating some rust on the M3 coming at the end of the week, it would appear that both the Hammerite and Jenolite products do pretty much the same thing is there a better one and a worse one?

plan is to strip with a motorised wire brush/flap disc, then apply the rust stopper before finishing with a decent coat of Hammerite underbody seal  There is nothing that can't be fixed with a hammer😜😜

i’ve just used hammerite on the FF’s rear drop arms cos they had rust on them...brushed on easily and looks ok..
time will tell if it cures the rust.. ... - .- -.

POR-15 is my go to brand
If you put the time in and prep as instructed it’s fantastic stuff
I use the degreaser, metal prep and paint .. it can’t be compared to hammerite 4.2 SC - sold , now bought back

In my experience the only way to get rid of rust and keep it away is grind it off down to clean metal then seal / paint the metal. Otherwise it will come back.
