I would be more worried about getting lost in a fog of clear overspray. Beyond that the overspray is going to drift pretty far. I hope your neighbors are far away. Cover your cars and anything else you care about.

Have any of you filtered your exhaust air? Would that solve the problem if you are in a neighborhood situation?

To add to my previous comments, I may only be spraying epoxy, high build or slick-sand, and final epoxy sealer. I am considering the "pay a Maco painter to do it" for color and clear once I have done all the prep and blocking.
Is the epoxy and primer overspray as bad as it is for color and clear?
Am I better off setting up my booth in the open-air for these applications?

Clear is the worst by far imho. When you say residential it really doesn’t convey how close your neighbors are. If you are on a 50’ lot then you really have no business painting in your open garage or driveway imho. A half acre, maybe ok imho…

I am on a corner lot with a side-loading garage. The house next door is about 90ft away and the house across the street is about 100ft away. How do those numbers look? I don't want to "That Guy"

That’s what I did in my home made booth. Use paint booth exhaust filters.

Don
Something like this? I assume it would cut down the amount of paint or clear that was discharged but perhaps not the vapors.

To be honest I don’t know where the line should be. It will depend on prevailing winds and the material etc. If it were me I’d build a booth with some exhaust filtration and I’d also have a conversation with my neighbors to make sure they are cool with it.

Another thought is renting time in a spray booth. I'm in the Seattle area and know there are several facilities set up for this. I assume other major cities have as well.
Kind of a hassle and you need access to a trailer. But presumably a commercial booth for rent is going to have good ventilation as well as a quality air delivery system.

Just shoot it at night :)
I belong to the Nextdoor App for my neighborhood. I've seen posts where people lose their minds over the next door neighbor using static sheets in the dryer and the fumes are "making my family sick."
Can you imagine the melt down over Urethane paint with ISO's?
Grateful I'm on 5 acres and a neighbor would have to be trespassing to smell paint . . .

The whole "paint my car in my shop/garage" thing is a "boil the frog" journey. Good to be aware of that up front.

It starts with "I need a spray gun."
Then "oh, I need ventilation."
Then, "a 3M respirator isn't enough protection, better get a fresh air hood."
Moves to "crap, I have a Harbor Freight water trap and really need a good filter/desiccant system or air dryer."
First primer shot and I say "wow, I couldn't see anything while I was shooting, need better lights."
And it goes on . . .

It's all worth it to some (me!) but not everyone.

Yup. And then I wake up at 4 AM and cant go back to sleep thinking of all the stuff I need and when to get it to stick to the budget.

You have all given me much to consider. Thanks for the sobering information.

Well again thank all of you for your replies to my original post and I appreciate the additional information that has been provided. It is all good and brings up some things I hadn’t thought a lot about.

I was originally asking about workflow – do I move down the car in the direction of the airflow or against it. In other words do I want the overspray to land on the unpainted areas or the painted areas. What I believe I learned was I should move down the car in the direction of the airflow.

Originally I thought that my fans would be placed to pull air out of the area but what I heard, and it makes more sense, is that I should place my fans on the intake side and filter the air coming into the “booth”. Pressurize the booth somewhat.

I still need to work out the issue of filtering the exhaust. I want to paint my jambs, door edges, etc. so hopefully that will give me a chance to experiment a little on some smaller areas before doing the whole car. Perhaps pushing the exhaust through filters and adding a water mist might help.

Any other suggestions on any of this would be appreciated. Thanks again.
