Evening all,
Please see photos of rust spots on rear silencer. I know the silencer is “double skinned” and I suspect this has been caused by previous owner/storage company running the car for thirty minutes or so, to top up the battery, resulting in water build up in exhaust? I’m thinking of sanding down, applying rustolem, and spraying with high heat gunmetal paint. Good or bad idea! Thoughts welcome. Many TIA. Neil
Rust spots on silencer... should I be overly concerned?

Hi Neil,
I am sure many of us have had the same rust spot problem, and my treatment was roughly the same as you propose. Luckily my chosen MOT man is a classic car fan and understands the silencer construction.
I believe that the rust, and even a hole, on the outer skin of the standard exhaust does mean a leak, nor is it necessarily under pressure from exhaust gases.
Somewhere I have seen a cutaway photo of the silencer box. If you can find it I anticipate that it should satisfy an unfamiliar (!) MOT tester if you have a problem!
