BMW Z3 M Coupe Sill Rust

‪@RedishMotorsportbmw‬ show how we tackle Chassis-bound Sill Rust building up on the BMW Z3 & M Coupe models. This is hidden rust behind the Outer Sill Panel.
This owner had just recently bought his M Coupe and after watching our other video on Front Sill Rust:
• BMW Z3M Coupe Undersid...
he saw he was also suffering with this common problem.
He made a booking with us to rectify the Front Sill Rust.
However, on removal of the Outer Sill Panel we discovered the Rear Sill section was actually suffering with rust worse than the Front Sill.
So a decision was taken to take care of the Rear Sill rust (and Central) whilst we had the Outer Sill Panel removed and had advantageous access.
You can see we use a mixture of @POR-15 products to neutralize any embedded rust, and then protect the bare metal.
Then it's on to High Build Primer, Sprayable Seam Sealer, and Top Coat Colourings.
Once all paints & sealers are cured overnight, we carry out the all-important Cavity Waxing and make a good point to show some interesting video angles from underneath.
If you have a BMW Z3, M Coupe, or M Roadster and are suffering from this very typical Chassis-bound Sill rust and would like to get it treated to an extremely high standard by a BMW specialist then please get in touch:
