I know Puma's seem to have this curse (small rust blisters on the edge of the rear arch).
I just have one but can't seem to get it to stop breaking through.
Have had it back to bare metal a few times and used a few anti rust prep solutions to pre treat it pre primer and then some Ford touch in paint.
Any more suggestions to eradicate this. A pain. But do not want to farm out to a spray place - as why shoul they be able to kill it (and if they can't and it breaks through you know there will be bugger all you can do to go back to them and not worth it on a 11 year old car (even if the rest is in top nick). It is only about 1/2" square (maybe a bit more now rubbed back). Don't care it it is a perfect finish just so that it does not keep breaking through.
