painting metallics on different days

[Don Meyer]

I would like to paint my cars body first then paint each component separtly as I get it ready. One of the colors is silver.

Is it possible to paint silver components on different days with out seeing a difference when installed?

I am 73 & do not have the stamina to paint the whole car at one time.

Yes, it's possible. You want to have conditions as identical as possible. Room temperature, air pressure, paint mixture, gun adjustment, spraying technique, should all be as close as possible at each spraying session. Use "good" base coat material, I'd recommend something that dries to a thin polyester coating like DuPont Chroma Base, Diamont or Glasurit and try to position the parts the way they will be positioned on the car, stand doors vertically and lids horizontally. Stir the paint VERY WELL before you start and before each spraying session, any sediment that is not in suspension can drastically change the color of later coats.

Len, whey you say to stir the paint, do you mean shake it?

Does the amount of time the paint is in the shaker, and the amount of time between when it's shaken and sprayed matter that much?

meaning, if you spray a hood with the paint coming just out of the snaker for 2 minutes, then spray the decklid on with the paint being in the shaker for 3 mintes, with a 30 minute delay after it was shaken, will that effect things?

Metallic base coat paint can settle out and the metallic can coat the bottom of the can. If you don't get ALL of the metallic in suspension before you remove any paint from the can it will cause less metallic when the first paint is removed and could cause more metallic when paint is removed later. This means that you could see a significant difference in color from one painting session to the next. If it were in my shop I would shake the can before using it but if you don't have a shaker then do whatever you need to do to mix the paint well. Different paint settles out at different rates so be sure to stir it well every time before you remove paint from the can.

Just to illustrate... this door was painted with the same paint as the rest of the car, but with different pressures. Metalics are picky about that.
