Dust magnets.

I see these "swiffer" dust attracting cleaning devices on tv, and I wonder if there is something you could do to a car to make it repel fine dust. Perhaps you could put a small charge on the body of the car to make it resist dust (to a certain extent).

I'm sure I'm not the first one to think of this, but I've never heard it discussed. I made a C in Physics III, so I'm not too keen on electricity. Seems to me, if you can make a rag of towel (that is safe) that attracts, you can also do the opposite.

There are both negative and positively charged dust particles floating around in the air at all times. These particles will be either attracted or repeled depending on how your car is charged. Like particles repel and opposites attract. But thats not all thats going on with dust. It also has some mass, albeit very small, so gravity is working against you too. The only way you are going to keep dust off your car is to enclose it inside a down draft clean room equipped with hepa filters. Even then you can get particles as small as 0.001mm.

there was stuff the paint shop sold you would dump it in ppg bob cat thinner it was green and was for dust before you painted i used if all the time 20 years ago but do not remember . old timers . here are some tips alot of junk comes out of the gun make sure it clean clean clean . off the cup of the gun and the hose i all ways used a old tack rag and went over the air hose and you . and ways grounded the car not sure if that worked but did it anyways

yep, ground the car, don't charge it.

I had a black Vette that I used to use Zaino Bros. products on. The guy I sold it to hasn't washed it for 3 years, just uses a California duster on it...it still looks better than new. I recommended Zaino to a friend that just bought a new black Vette..he gets compliments all the time. This stuff really works
