Its not totally controllable.

Of course if your using an HVLP you will have less overspray.
You will have less when you spray primer and base as you use lower air pressure.

Clear will be the worst as you use higher air pressure.

Cover anything you want to protect as its easier to do now than clean it off later. Lots of plastic sheeting.

Barry is right (as usual).

I am doing a 67 also and I have sanded more overspray than I care to admit. It gets everywhere. Sanding INSIDE doors, etc is no fun.

I like the plastic masking material you buy. Mine is 3M and 16' wide. Its easy to wrap around stuff and does a great job. So mask everyhthing.

Its all work !

There is always overspray. If you have a conventional gun cranked up to 50 p.s.i. spraying clear, there is lots of it. It is very important that you have proper ventilation in the area you are spraying, hvlp or not. Nasty stuff is in the hardeners, so make sure you cover exposed skin, eyes, and have the proper respirator. Hard to enjoy a newly painted ride if you ruin your health, blow the place up or worst. Don't want to scare you but just want to keep that part drilled in peoples heads. Many people have not followed saftey, myself included, but there is always the chance of severe consequences of both igniting fumes or getting overexposure and ruining your health or possibly not waking up in the morning.

Hahaha. And what would be worse?

I think if I ruined my health AND blew up my garage that would pretty much be it !

To reduce overspray inside the doorjambs and between the fenders and hood, I always use a round foam tape. If you use foam tape when spraying primer, you should replace it before painting.

Also make sure everything is taped properly and that it will resist the pressure of the gun. Using a "tack rag" between each coats of base coat and before the clear is also a good thing. Don't use the "tack rag" between coats of clear .

A last solution that could help reducing overspray is to paint the car with base coat and to clear each part at a time (hood, fenders, doors, top) when the rest of the car is taped. I never tried this method but I think it could work pretty well but you would have to use a lot of masking paper and tape.

Good luck on your paint job.

Bad would be if you blew up your garage or got too much exposure to iso's and chemicals. Worst would be if you were in the garage while it happened, or got enough exposure the iso's to kill you. I don't remember the whole story but read about a guy who painted a car and felt sick that day. Next morning he didn't wake up.

Good ventilation helps too. Getting overspray out of the area will prevent it from being available to settle on anything. It's a problem for sure and an ounce of prevention is a big step in preventing it.
I use the cheap thin plastic "drop cloth's" to drape over area's that are tough to mask off/out like interior's,engine compartments/engine's taping where necessary and just toss it when done,It's cheap and much easier to use for some things than paper. Old sheet's and trash bag's are good as well.
