What is it? read this Plus there is loads of videos on Youtube to see it in action. Just search Iron Out or CarPro Iron X. CarPro were the first I think.
Used this at the weekend, wow!
First couple of time I washed the Merc I could feel the drying towel catch a bit on the bonnet and roof. I guess the car has been standing for a while who knows where.
I tried a light clay and it helped but there were still a few spots like this. Probably more I could't see. These pics were taken after a 2bw and Autosmart Tardis wipe down, rinse and dry.
Then i used the Auto Finesse Iron Out. It turns all the iron contaminates purple as its working. Safe to use on any part of the car it doesn't matter. Just don't use it in direct sunlight.
Could't believe how much contamination there is that you can't see. Even after a bit of claying last time washed, and tardis wipe down this time round.
The rubbish pictures don't show it very well, you really should have a look on youtube.
After this I didn't feel the need to clay again which was a good job because I left it at home. Doh
A good rinse and dry and it's ready for polish/wax/sealant or whatever.
Warnig! This stuff STINKS like nothing you have ever smelled before.
It's also really good on neglected wheels to.
