Attempting to retrieve painted image from rusted galvanized sign

[galvanized]

hello.
I am wondering if there is anyway to retrieve a painted image from a galvanized sign that has rusted over.
The original logo/name was likely painted in black stencil over galvanized sheet metal. I have not seen it in person yet, but from pictures it looks like image is gone and whole sheet is rusted.
Is there any chemical process to retrieve the outline of the image?
Thanks!

maybe toss it in a bath of aqua regia and see what develops

Hello,

Thank you for reaching out. I understand your curiosity about retrieving the painted image from a rusted galvanized sign. While there may be some chemical processes that can potentially help retrieve the outline of the image, it is important to note that the extent of rust damage and the type of paint used will greatly affect the success of such a process.

One potential approach could be using a rust converter solution, which converts rust into a stable compound that can be easily removed. This could potentially reveal the painted image underneath. However, this method may also remove any remaining paint on the sign, so it is important to carefully consider the risks.

Another option could be using a paint stripper to remove the layers of rust and paint, revealing the original image. However, this method may also damage the underlying metal and may not be suitable for galvanized sheet metal.

Ultimately, the best approach would be to consult with a professional conservator or restorer who has experience working with rusted metal and can provide a more accurate assessment and potential solutions for retrieving the painted image.

I hope this helps and wish you the best of luck in your efforts. Thank you for your interest in scientific methods and processes.
