Does the panel have to be dry?
I recently got a bottle of this and was thinking of giving the car an iron decontamination. There's probably some light dusting on the car's paint at the moment
Wondering if I should hose down the car and while its still damp, spray the fallout cleaner or do I need to dry the whole thing first? Or even better, just spray it as is [car isn't exactly dirty dirty, just some spots with dust].
Great questions.
The normal recommendation for using most iron removers is to
First - Blast any loose dirt off the car.
Second - Spray a panel down, allow the iron remover to work for a few minutes and spray off the residue before it dries. Repeat this process panel by panel to the entire car starting at the top and working our way down.
So if you want to be safe - follow the above routine.
Me?
I spray down a dry dirty car as the film of dirt holds the iron remover onto the paint to enable it to do it's work. Then I wash the car with a foam gun.
Then I rinse off the entire mess and the re-foam the car and then I use a Nanoskin towel or a Nanoskin mitt to mechanically decontaminate the car.
The above is my approach as it serves my purpose.
What's my purpose?
Well most cars I work on are in
HORRIBLE CONDTION so I'm going to do an extreme show car makeover. That's my history in the car detailing world. So when I'm washing a car in horrible condition my goal is to get it as clean as possible to prepare it for the machine polishing step.
If the above does NOT describe the kind of cars you work on of the kind of car detailing you do then my approach probably isn't for you.
