Ground your chassis before painting?

[dibbons]

I was told to wet the floor of the paint booth before beginning to spray and also to wrap a large chain around the differential and let it lay on the floor to help ground the chassis and help to repel dust. I tried it but cannot vouch to this technique's effectiveness.

I've always done that. It seems to help, but that's completely anecdotal.

First of all, you are introducing moisture to an operation that we as painters are trying to avoid!! The whole reason we use water traps, and golfball air filters. As the water on the floor evaporates it goes up, and up is where your car is. As for the grounding of the chassis, my old boss did that religiously. It worked for him, because he said it was reducing static electricity. Did he still denib a paint job of dust particles? Yep, every time! I have never done it, but I also sand and polish every job I do.

I should mention that I don't wet the floor, but I do ground the chassis.

seems to me u should have enough airflow through the booth that humidity is pulled out?

my floor is dirt so I wet it! LOL

my father in law has painted many cars in a back yard shop and he wets the floor all the time but I have never seen him ground the car

I wet my floor down as well but I wait until it is almost dry before I start. I also bolt a chain to the car and drop it on the ground. Whether or not it actually does anything I don't know but I've never ended up with dust stuck in the paint

I see a very good reason to ground the chassis, static charge build up. That will pull stuff like a magnet.
