When I bought my RS5 in October last year I asked for a little ramp time to inspect the underside. What I noticed when it was in the air was a the beginning of a little corrosion on some of the chassis structure. The factory black cost has some surface rust. It has always been on my to do list and get this addressed. I know no one will see it but I know it’s there. Anyway, having some free time over Easter weekend I’ve put the car on some ramps, sanded and wire brushed and got the first of two coats applied. It’s actually very difficult to get it all covered as exhausts, petrol tanks and struts all get in the way. I’ve done what I can, so here’s a few pics. I’ll apply my second coat maybe tonight or tomorrow. Knowing this is addressed gives me peace of mind.
Some pics of my ramp time pre-purchase and also after first coat today.

Nice job done there Mr F. That should hold it at bay a good while.

Danjwildon, thats exactly what I want, get that chassis coating restored to keep even the unseen parts rust free for a while longer. The second coat is now applied.

X3me, what I’ve got is Obsessive Coating Disorder, it’s highly contagious. You could get it by just reading this post 😂
