While I had both front and rear undertrays and the diffuser off I thought I’d give them a quick clean.

The rear undertray was pretty filthy!

The Union Flag decals, fitted by a previous owner, were looking pretty untidy now too so I got rid. I have something different to go in their place.

Mid clean, still some of the decal adhesive to remove.

Much better.

New stainless steel fixings for the front undertray.

A light coat of ACF-50 before refitting the undertray.

Fitted with a decent amount of corrosion block grease on the threads and washers.

Same for the rear end.

Plus some new decals.
