Buy new shock mount nuts and any other steel part that has zinc coating failure.
Here’s more pictures of the shocks removed.
(They mounts look new) But silicon was inbetween the body, and mount. Instead of the oem gasket that it calls for. So I used a wire brush and remove the shit from the mount. I am now using 400 grit sand paper. And hopefully getting rust converter before I reinstall.




As you can see the mounts got scratched up from wire brushing the silicon off.. Should I just get new ones since that could lead to more rust?

Does not look too bad at all. Hopefully you won’t find more when grinding that off.

Lighten up man, its a joke.
I would actually prefer to do it with a power tool/wire brush as it will be faster and more thorough. Once you get to bare metal, make sure you seal it, and seal it well. Dry before re-installation. Your mounts look fine.

Results so far..

Deff needs more sanding. And I need to research products.

Home Depot had these products.

Someone said to use rust converter. But will these work?

I wouldn't use the last one. Primer should be just fine.
None of these are rust converters, btw.
You need something like this:

But like I said, just primer should be fine, granted you got rid of ALL rust.

I wouldn’t use any of that. Get proper paint and metal prep at an auto body shop. Home Depot repairs are tacky. SEM EZ-coat has a variety of colors that match the OEM underbody colors.
