Suggestions for spot removal

[sharpgator]

I have a spot on my door that has presumably been there since delivery. I’ve rubbed the door down with BKF a couple of times without success. When looking at it up close, it’s very hard to notice. However, in certain light, it’s very obvious. Any thoughts on how I can fix this?

Which BKF? I’ve used the paste with the blue Scotchbrite to remove similar stains, but it takes gentle scrubbing (and repeated applications in my case).

The only thing I've ever heard of to change spots like that is to re-passivate the entire panel.

Wow, what a weird blemish.

Personally, I'd ignore it. As the truck darkens, it'll be less noticeable.

Have you tried Citrisurf 77 as recommended in the owners manual?

I was ignoring it. Until today when I saw it in this lighting. Looks like a zit.
I’m not quite sure if it’s a stain or a place that’s been buffed by the SC prior to delivery. Or…is that the same net result?

I have. It’s a little hard to isolate my work a spot that can’t be seen at working distance

I wonder if passivating the entire door skin with Citrisurf would make a cosmetic difference.

It should bring it all down to about the same. As you get closer to shiny, there's fewer and fewer ions for the acid to react with.

I had a similar discoloration on a marine panel. I used Aqua Armor Stainless steel and more, It evened out the finish and has Si02 Nano Ceramic to aid in longevity of the finish. I started using this on my truck and have been pleased with the result.
