I'm looking to refurb an exhaust system and flexi I have.
The stainless part of the system has come up really nice with some fine grade wet'n'dry and water. However, the flanges are steel and very rusty.
Initially I'll get a wire brush on them but my question is....
Can I then put a rust treatment product on the flanges and flexi section (before using some high temp paint)?
