G650GS Swingarm Rust Repair: Sanding, Primer and Paint

I took the swingarm off my BMW G650GS to replace the chain, the hub dampers and the shock.

So I decided to deal with the rust on the end of the swingarm that had been bothering me for a while.

Rust on the rear end of the G650GS swingarm, where the chain is adjusted.

This is the very back of the swingarm.
It's where the chain tension is adjusted, and it's rusting from the end.

Rust on the corner at the end of the swingarm.

This is the state it was in.

Sanding off the rust with a micro polisher.

First, I sanded the rusty areas with an abrasive disc on a micro polisher.

It makes sanding easy!

The end of the swingarm with the rust removed.

The rust came off nicely.

The other side with the rust almost all removed.

This side is mostly rust-free now too.

Degreasing with silicone remover.

Before painting, degrease it with silicone remover.

The masked swingarm and Mitchakuron primer.

Mask the swingarm and apply Mitchakuron (an adhesion primer) as a base coat.

Leaving the Mitchakuron primer to dry.

Let it dry until it's ready for a top coat over the Mitchakuron.

After that, I finished it with black car paint.
The black on this bike is semi-matt, but I didn't want to buy paint just for this, so I used some gloss black car paint I had left over.

Silicone remover comes in handy for lots of maintenance jobs, so it's worth having one.
