Dear sir
How can I prevent industrial fallout paint defect from vehicle external surface?

You need to clarify. What do you mean by "industrial fallout paint defect"?

And what does the vehicle have to do with it? Are you speaking about some paint defect on a vehicle? If not, please clarify.

And if so, please clarify what you mean by "industrial fallout".

Are you speaking about something like this?: http://www.waxnvax.co.uk/specialist.html

Hi dear
I speak about paint defect on vehicles when parked in industrial area because of industrial fallout
I need peventive sulotion for this problem

Hi, saeid2000!

Are you asking about debris or splatter that might fall on to cars from an industrial working site?

Thanks!

Hi clough
Yes I ask about industrial pollution that contain very small metal particle

Hi again, saeid2000!

One of the things that I do for a living, is that I'm a house painter. If there was danger of paint getting onto cars nearby where I would be painting, I would be asking people to move their cars or to put up a plastic shield so that the splatter of the paint wouldn't get on their cars.

Is that the sort of information that you're wanting here?

Thanks!
