The mazda is covered by panels, which protects the undercarriage, but the area where the control arms and exhaust is, is exposed. As you can see in the pics, my surface rust is mostly on the right control arm, the exhaust, and the connector that connects the mid pipe with the exhaust.
Exhaust is no problem as this can be replaced with aftermarket, even the mid pipe can be replaced.
What can I use to remove this. I suppose a grinder and some rust removal chemical. My concern is using any of these rust converters and possibly causing more harm than good like the rubberized undercoating shit.
I applied some w40 and it helped a little, it looks a little better than these pics.
I know a place than rents a garage and lift. I figured I could take it there and do my own work to remove it. I'm looking to remove it. I don't trust this "rust converters"
No such thing as "converting " rust. You can use various chemicals to turn it black or purple even pink but it is still rust living in the metal . You can cover it up with any of the wonder snake oils but it is just covered.
If it was that wonderful you would see high end restoration shops swearing about it instead of swearing at it
