I just bought a new, outside rearview mirror for my car but I need to spray-paint the mirror before I bolt it to the car door.
The directions on the spray cans of Dupli-Color Perfect Match paint say to allow "sufficient" time for the paint to dry between coats.
How many minutes/hours of dry-time should I allow between:
* each coat of Scratch Filler Primer
* the last coat of the primer and the first coat of the color paint
* each coat of the color paint
* the last coat of the color coat and the first coat of the clear coat
* each coat of the clear coat
* the last coat of the clear coat and installation.
between primer coats, then a half hour to the finish, then a half hour
to the clear coat.
In your case, I;d wait a bit longer, even overnight from primer to
finish if you can.
There are some paints that will say to coat withing an hour or wait at
least 12 hours, but if not stated, it probaly does not matter.
The question becomes, what about that "within an hour"? 5 minutes or
55? 1 or 59? or 30?
I'll generally stray something other than the "prime target" and
assess the progress of drying or curing by touch on the "test sample"
to decide when to recoat, or sand off runs, or whatever - without
risking damage to the "prime target"

I do my spray painting in the shade, but outdoors. Often in the hour or
two before sundown. I don't want to inhale the slightest bit of
paint, not even the stuff that sneaks around the mask or respirator.
And on a calm day or when the wind is blowing away from the houses and
the cars. Overspray can travel a long way. I do have an advantage
of 200 or 300 feet of woods in one direction. But when I've spray
painted a car -- because of the layout, I can't get my car into my side
yard -- either scratches or more, I drive to where there is no one and
nothing around, in any direction.
I used to put newspaper on the grass to avoid painting the grass, but
periodically I go around taking down the illegal advertising on public
land around here, the plastic sheets on metal poles. And I realized
those plastic rectangles make even better cover for the grass, because
it takes 10 times as much wind to blow them away. When it's windy
enough to move them, I wouldn't be painting anyhow.
I definitly paint on the grass and not a sidewalk because even though it
looks like the protective cover is plenty big, sometimes it's not big
enough. When paint gets on the grass, the grass gets mowed.
If so, half an hour between primers (unless you are sanding) but why
3 coats? then half an hour (or less) between colour coats (unless wet
sanding) then half an hour between clears (unless wet sanding)
If wet sanding, allow at least an hour or two before sanding - then
coat immediately after the item is FULLY dried from the sanding
mixed" or dealer supplied touch ups. For mirrors and other accessories
it is generally so close you cannot tell the difference, while using
it to spot repair a panel is a "horse of a different colour", and even
to paint a "defined panel" like a door can be off far enough to be
very noticeable becaue it is on the same "plane" and even between two
other original panels.
Auto paint stores sell a little sprayer that uses a baby food jar and
a separate can of propellant.
They can mix just about any factory color, the problem that color has
probably faded if the car is a few years old.
