Thanks I'll have to check it out, those spots are my only complaint about the Pure White
Iron-X is a wild product to use.
If you like to see if something is working this is it.
Suggestion. Get Lemon scent!!!!!!!
I have Cherry and it smelled so bad had to keep the bottle in my shed.
Smelled like a skunk. I thought it was he product but Lemon is not as bad.
Suggested use.
Wash car as normal. In the shade.
Let drip off but not dry.
Spray Iron-X on a panel at a time.
Let it sit 5 min - enjoy the show.
They with Micro fiber cloth wide down the panel and spread out Iron-X.
Hose off panel. Do next and repeat.
When done lightly was car again. Snow foam application will do if you have.
Dry car well.
You can clay now if you want.
Might be good to allow time to wax as the Iron-x will likely remove wax that is on car.
A long day but worth it on white.
Do maybe every 6 months. After winter, late summer.
Try it you will be amazed what washing leaves on the car.
To not scare anyone.
When you apply Iron-X, in 30 seconds you will see purple streaks fork as the product reacts with iron oxide. You will be amazed how much even after washing.
Do not let it dry. Wash off if drying to fast while it sits. This is why early spring or later fall would be good to do it.
Search on you tube and there are likely videos if you want to see before buying.
