Paint the roof first. I use a couple 10 foot long benches to paint the roof, and I have a nasty habbit of dragging the hose on the car, so if I can, I like to do the roof a couple days before I do the rest of it. If there is a belt line trim, I mask the car there. this keeps the dry spray off the trunk and hood.
The roof is much easier not to dry spray when you are doing the rest of the car than the hood and trunk.

I had a fly land on a 59 Volkswagen deck lid after all the clear was sprayed. Worst thing was the fly split open and little baby maggotts started crawling through the clear. They all buffed out Ok though.

Hey
This is like hard for me to explain but I'll give it a try, when you're painting the sides of the car you go across not up and down but when you're painting the bonnet. (Say you're facing the front of the car, do you go across or up and down? ANd same question with the boot? And roof. Have a good one all! Great post!
Thanks
Troy

I paint the top front to back, one side then the other, so there is no dry strep in the center. The hood is the same way. The trunk I go side to side, depending on the body style.

I wonder if the guy who suggested bottom to top had an 'updraft' spray booth. Maybe the electrician hooked the 3-phase power up backward.

I work in a body shop that is pretty big and I always paint from the bottom up, and never had a problem with overspray. You will have the same results going from top down too. either way you are going to get some overspray. not like the paint just magically floats over the panel if you spray from the top down. You always have overspray.

If you start at the bottom, then the top will have over spray dust on it and you will be spraying paint over the dust.

I say go from top to bottom, don't fight gravity, work with it. If you have a run, you can chase it down and clean it up.

Also, what if your body or clothing brushed up agains the car when you are painting the roof, would be a lot nicer if there wasnt already paint on that side.

Most interesting answers.

I think everybody is right!

I never start in the same place but I always start at bottom only for reason of I can do final gun adjustment if not laying right and second just in case something was in the gun and want to shoot out. I'd rather screw up on a rocker than in center of roof or hood.

Sometimes flow of booths could demand where you start and finish.
But really, who gives a crap as long as the job turns out the way you want it to??

Over spray on roof? I've really never ran into that problem since lacquers.

Good points BarryK. The flow of the booth is important. I almost always start close to the exhaust fan. Here in Florida the season of the year makes a difference where I start a coat. When it's 90 plus degrees the roof, trunk and hood get sprayed first to avoid me dripping a sweat ball on the vehicle.

As far as overspray landing on the roof, Chroma base was bad in hot weather for spraying dryish. Don't use it no mo. Other than that if your booth flows pretty well, over spray is not a problem with todays paints.

i have a paint booth with a downdraft. If you are having that big of an issue painting going from bottom to top buy a better gun. I start from the bottom because i dont like the clear being dry and if you go from top down your not as likely to pay attention where the gun is. Its easier to stand up from a good low position then squat down, thats my theory on that. besides either way you paint, the air pressure is going to push the paint particle all directions on the pannel, air pressure wins over gravity.

Humm, Who's having an issue painting from top to bottom or from bottom to top? I guess we all need a few lessons in painting.
