I’d tell your “friend” to gently remove corrosion with red Scotch Brite pad, apply ACF50 with a paintbrush, (mostly to conceal) and trade the fucker in on new shiny one.
I did it all, I treated my 1200lc like a baby, I think that's why it was such a blow to be left in the cold by BMW. It's not lack of care or protectant that leads to engine paint corrosion
This.
Beautiful
Same here, a little care goes a long way, the bare, brushed aluminum cases on my 13,000 mile 2017 Thruxton R are almost as new because of a frequent wipe over with ACF 50 or similar product.
Thats one stunning bike
I suspect that the answer is no - I'm sure you could clean and sand down the affected area and give it a re-spray from a can or brush on some paint as a way to stop the 'rot' spreading, but the only way to get a really good finish would be to have the individual parts removed and professionally re-finished - but I have never tried it, so I could be talking bollox
Mine were replaced by BMW under warranty two months before the end of the three years but I had planned to remove all the loose stuff and use Hammerite smooth. IMHO if you can't do it properly by removing the bits and getting them treated and sprayed professionally, or can't afford it etc. then you might as well use something that will definitely work and you can forget. I think if you spend care on the preparation you should be able to get a half decent finish and it's very tough. Sometimes, you can only do your best.
I suspect it is easier to get an acceptable finish on silver finish by polishing etc than it is on black.
