Hi all,
Listerine is developing a nice 2-tone effect on one of the arches. Now, it’s not chronic yet and the car’ll never be a showpiece, but I’d like to hold back the inevitable metal and paintwork for as long as I can.
As such, are products like THIS any use? Just to try and hold back the tide, as it were.
Thanks in advance people 
Generally, corrosion on the arches either comes from inside, or from where the paint has chipped of on the lip.
If it’s from the inside, then it’s already started and most probably unstoppable without replacing metal.
If it’s from stone chips on the lip, and it’s not gone too far, then painting it will usually stop it.
Thanks chap
Yeah, the exposed rust is certainly from the inside-out. Paint becomes bubble,s becomes brown. I totally accept that I can’t save the day without new metal, I’m just wondering if painting this rust-cure stuff in the arches will do anything to slow the rot.
Rust cure is only any good for neutralising surface rust.
Where you’ve cleaned off the surface rust and then treat it before painting.
I had a bubble appear on my XR3i many many years ago, was caused by a layer of foam sandwiched between the inner and outer wheel arch. (maybe Ford thought this was a good idea)
From the inside, I removed the foam and then filled the offending hole with body filler, and painted it.
Then from the inside I protected it with my my own wax oil recipe using grease and isoproponal (i worked for the NCB lol)
It seemed to work whilst I owned the car, but would be a bugger for anyone attempting to weld it later.
