Painting piece by piece?

Hello, I have done some painting in the past, but this will be my first time painting an entire car and first time with base coat/ clear coat. I have a couple questions. The car is completely taken apart. Is there any disadvantages to painting doors, hood, etc while they are not mounted and not painting it all at one time? Also, it is getting colder and I the garage furnace is not hooked up yet. Is it alright to finish priming in the 50s and 60s? thanks,
Bill

I'm going to read the article now but in the meantime here's my take on it. If you're very meticulous with the details it's ok to paint in pieces on different days. Try not to adjust your gun settings and always work out of the same batch of paint if possible. If you need to go out and buy more mix it into whatever you have left from the original to keep from having variations.

Also make sure you use the same number of coats on each part.

Most people won't be able to ever see a difference if you do it right...especially if you wetsand and buff after spraying.

One additional thing I like to do, especially if I'm painting in pieces
over an extended period of time. especially metallics.
I like to mix a gallon real good and pour off 3 quart cans leaving 1 quart
in the gallon to be used first.
If you always pour off from a gallon can, chances are it will be different
on the last bit to be used, especially metallics settle and float faster
than you can keep it stirred.
By pouring off from quarts instead of one big gallon, you minimize that.

Thanks for this thread...and especially to Brian for his write up. I'm right in the middle of pondering the alternatives for how I paint the sedan/delivery and this info is going to be very helpful.

Yup, Nice write up Brian.
I'll put it this way,
Metallics are fickle enough as is.
I'll do the "insides" as panels but shot at the same time.
The outside WILL be shot together and at the same time.
All done with the SAME gun and SETTINGS as well as mix.
Solid colors are a little different.
As long as you have a CONSISTANT primer color and enough coats to achieve COMPLETE coverage,it's not a problem.
I proved this with my test previously and this was over different primer colors which made NO difference as long as you get COMPLETE coverage,in other words,OPAQUE color achievement.
ANY paint will turn out "different" depending on coverage. Metallics,Pearls,Kandy's ARE coat DEPENDANT as well as primer color.
You use the wrong shade primer and add more coats then necessary,you end up with LESS or MORE than DESIRED color. Most custom colors REQUIRE a SPECIFIC primer color and NUMBER of coats to achieve the DESIRED color.You deviate from ANY and you get what you get.
Panel paint is fine for some aspects of the job but for the OUTSIDE,
It WILL be shot TOGETHER.

My "warning" still stands to have all panels the same substrate color, be it a solid color or metallic. The reason being, WE may know when complete coverage is achieved but not everyone can.

It eliminates that one variable that can cause a problem.

Hell, I have made the mistake, and I am nearly perfect.
