Small rust pittings were cleaned and treated with Brunox rust-stop, then covered by an grey etch primer paint. Where I took of the bottom sealant got filled in with Polyurethane seam sealer. The full bottom then got a black Sikagard 6470 rubber underbody coating, which stays flexible in stead of chipping off like the harder underbody coatings. And then the rubber coating got a full 2k hellrot respray. Hoping it should be good-to-go for another 5 tot 10 years!
Normally only the rubber coating should also be fine. And can also be bought in the grey creme like OEM colour, in stead of black. But I'm really liking the red and it makes it fully fresh again.
If you do, don't forget to reinforce the rear trail arm and shock mounts, while you're in there. And as your car's a real m3 the subframemounts should already be reinforced from the factory! Definitely is going to look awesome in yellow!
