Chrome spray paint test -
I bought six different brands of aerosol "chrome spray paint". As an aside, each one had a cap which was bright and shiny, like spanking new chrome bumpers back in the 1950s.
But what you see on the cap is very different from what you get in the real world. Imagine that!
I wanted to see just what each brand would do, if used on (1) a shiny sheet of tin plate, and (2) a sheet of tin plate that had been sprayed with flat black paint (several years ago). Didn't exactly want to try my tests on a brand new chrome plated bumper. I'm not quite as dumb as I look! (Mickey - don't say a word ...)
Following the directions on each can, I shook as directed, then sprayed for one second on a plain test area, and the black test area, all on the same piece of tin plate.

Each paint is numbered. In both the top and bottom sections, #2 seemed brighter and "shinier" (more mirror-like) to me. Number 5 was a close second. I set hex sockets on the lower section to test reflectivity.

Close view of samples 1, 2, 3. Despite the poor photo, #2 is definitely brighter and smoother than 1 or 3. Note also the hex socket has a clearer reflection in #2.

Close view of samples 4, 5, 6. Again, #5 is brighter, and "reflect more clearly", than 4 or 6.

The entrants -
Paint 1: DoItBest Silver Metallic, 781531.
Paint 2: Krylon Metallics Chrome, 1707
Paint 3: Rust-Oleum Specialty Metallic Silver, 1915830
Paint 4: Krylon Metallics Bright Silver, 1401
Paint 5: Krylon Original Chrome, 1010
Paint 6: Dupli-Color Chrome, CS101
To my eyes, #2 (Krylon Metallics Chrome) was closest to a chrome bumper. However, note that none of the paints examined were nearly as shiny as the original unfinished tinplate. Thus, even #2 just barely approaches the clear mirror surface of a chrome plated bumper.
More than you ever wanted to know, but I learned something. Even if the rust is completely removed, and (somehow) the area is polished down as much as possible, a "patched" area will always contrast with the original chrome surface.
Hope this helps someone. It sure helped me.
Thanks for reading through all this.
