I have metal paneling on my wall that got scratches from wiping with abrasive material (accident). The white stuff looks like parts of a "skin" when it gets rubbed on concrete to put it in perspective. Is this repairable without having to replace the paneling. I have this on long walls so the price will not be cheap if I replace them.
They are probably more noticeable to you than others. You might try a little bit of tooth paste and see if it might rub out the contrast. They do make a paint with type of finish but I would only do that as a last resort.
There is not much you can do. If it were a polished stainless steel, brass or copper yes, but you have galvanized steel. You see the crystallization pattern in the zinc. There is no way to polish out scratches without risking polishing off the zinc coating or leaving a even more visible buffing/sanding mark. Just consider the marks "patina" and go on with life.

So what was the material used? That will help a lot to understand what you have!
The first question is, do the panels have some type of coating on them to keep them from oxidizing (rust) that is important to figure out since you need to know if the repair is to the coating or to the metal!
If it's un-coated metal it would be an easier fix, just like the finish on a car you buff it out with an abrasive paste, getting to finer and finer materials.
He is using galvanized steel. The galvanizing is the protective coating. That's the crystalline look on the surface. It looks like the same stock used to form HVAC rigid ducts or possibly a galvanized flashing material.
As said, the wall panels appear to be repurposed galvanized sheet metal.
The galvanizing process makes the surface highly resistant to water but acid is what is used to remove the galvanized finish prior to soldering..
The finish has been altered and can not be restored.
To make it less noticeable you could try a cleaning product that leaves a residue like ArmorAll for vinyl or even baby oil.
Don't put any acid or strong alkali (including vinegar, orange juice or oven cleaner) on the surface. You will make the situation worse.
Toothpaste is safe. It is very mildly alkaline and is very mildly abrasive. But don't brush it very hard or repeatedly.
Galvanized metal is not intended to be a decorative surface when left bare. It needs to be dried off well after cleaning. It develops (usually whitish) water spots easily, which are a form of oxidation or corrosion to be exact.
I would like to pickup a new hobby: Welding
There is a lot different type of weldings which this is all new to me.
I watched a YouTube video that gave me a high level understanding to ask more questions.
I am not sure what I will be welding in the future but researching what are out there.
[b]What I do know that I don't want to play around with anything that is gas related or storing gas canisters in my garage. This would probably rule out MIG and TIG welding right?[/b]
As for safety, please share things that I should not be doing. Since it uses electricity, I am sure there are some danger that needs to be discussed.
I am sure that I will need the following right?

Hi folks, Hoping you could give some advice regarding a broken peace on my treadmill‘s circuit board. As you can see in the picture, there’s a female connector that gets soldered to the board and that’s where the display cable plugs in. It’s an eight wire connector and looks similar to an ethernet cable sort of. When I opened up the treadmill and looked, the connector was no longer soldered to the board. I’ve soldered things before, but nothing to a circuit board this tight before. When you look at the board, it looks like the metal is partially missing where this connector would solder on. Do I still have the ability to solder the connector to the board?
Thanks!
