My G had a ton of fallout on it so I did a fallout removal today and it worked great. I’ll share the process for anyone else who wants to do it
First off wash the car, and get it at least mostly dry, this should obviously be done in the shade. Get some iron-x fallout remover (it stinks), Auto Glym Magma, or something similar. I used Iron-X low odour, and it wasn’t too bad.
To do this you spray it in the car and wait a few minutes, then agitate a bit with a wash mitt or sponge, note that it will react with the fallout so you can see it work, pretty cool. Just don’t let it dry in the finish, which is why you do it in the shade. I did mine in sections, and even then some started to dry since the sun just went down, and the paint was still hot.
I’ve attached some pics of before (after a wash), after a quick spray, after agitating, and after rinsing and air drying (needs a very good rinse because the product will hide in crevices and keep dripping). Afterwards I did a good rinse of the driveway

What I used, got it from carzilla

 

I need to do that on my car, it's black so you would never see it but I know it's likely there.

I used some on my 2000 GMC Sierra 2500HD about 3 years ago and my ENTIRE truck turned purple, it was insane how much rust was embedded in the paint.

Also need to use some on my Ford Focus...

Thanks for the reminder

 

I saw this VW Rabbit yesterday, I wonder if the fallout remover will work on it too

 

Pretty funny but it actually seemed to remove quite a bit of the rust I had on a chip, lol…..I wonder how many applications it would take to really help.
