[I apologize. This post was supposed to to be with an interrogatory - this is an original panel from my '33 3w, with an afternoon of Bon-Ami, baking soda, water and cotton cloth rag. I submitted three photos with the prior post.
This panel-front had rust, but no pitting (to speak of.) But, there was one brown/black mark that had to be gently scraped off; upon pocketknife scraping, one ballpoint diameter pit appeared, lower right panel.
Then two pinpoint marks appeared with the Bon-Ami; and I noticed miniscule 'points' not palpable; visible upon viewing from different angles in sunlight. I think that these 'points' are ready to pop with rust. But this panel face is done, not to be touched again!
The panel back photo - which doesn't appear here - had serious rust, with a few little areas of pitted rust. The entire back was 'cleaned up' with a Brillo pad, ooo+- sandpaper, flat screwdriver tip for pitted rust, and Bon-Ami. Cleaned up nicely for being the back, including the machine-thread nuts.
The panel ring photo - which doesn't appear here was in similar shape 'sprinkled' with pits. I attacked it with the Brillo pad; surprisingly it finished gleaming, into the pits as well.
What was the Ford chroming process relating to the front of the dash-gauges panel and front of the trim ring being chromed, but not the back of the dash-gauges panel and not the back of the trim ring.
thank You.
