Little off topic....... I had a stainless King Cobra that I took some red rouge and started with then took some flitz and it looked like chrome. If you are wanting to go that route just a little info for you.
\/ \/ \/ what he saidOK...what's "red rouge" and "flitz"?
Red rouge is a very fine buffing compound and flitz is an over the counter polishing paste. Very good chrome and stainless polish. Reloaders use rouge in walnut shells to polish brass cases. Can be purchased in stick or powder form. Check eastwood or any other bodyshop supplier.
I have used angle grinders with wool bonnet polishing pads, used for polishing clear coat. Works pretty good with flitz. Flitz polish to me sounded like a joke till I tried it. It does a great job.
My stainless pipes on my motorcycle rubbed the ground on a deep lean turn, Once I sanded it somewhat smooth, I at least got it back to a shine. Nothing else worked but flitz
Also...those mirrors are very stainless steel looking...shiny but dull...definitely not like chrome
In old movies and TV shows they would smear a low glare substance on vehicles that were close to the camera. The mirrors were probably a good bit more shiny that what that screen shot shows. Notice the really dull paint on the windshield pillar?
