I painted my 67 GTO in October of 2011. I painted all the parts the same day, the car was apart except the doors were on. After the car was painted I buffed it all out and put the now buffed out fenders into the shed covered with sheets. Well they sat there until about 2 months ago. I installed the nose. My daughter came out to see the car and asked why the fenders were a different shade. I stood back and looked and they were a little bit off. Well now I have to blend the doors into the fenders.

Why would they be different, like I said everything was painted the same day. I even mixed all the color at the same time.

Different coverage or sealer/undercoat. Were they hung in the same orientation as the doors? Even though not metallic, some have a tendency to spray tops and sides differently.

Everything was set up the same for all coats. White epoxy was used before the base. It's not a side or top, it's the whole thing. I have been painting a long time and have never seen this type of thing.

UV Light altered the paint that was exposed and did not the paint that was covered ?

This is the exact reason the body shop I worked for started paint complete cars assembled. Fenders, doors, hoods, trunks all on the car before paint. When we started doing this we never had a paint mismatch again. Don't have a clue why it does it, even if the parts are hung in proper orientation while painting the color still tends to be off. Makes it a lot more work to get rid of the tape line at edges as you have to wet sand and buff them without burning through, but at least the colors are correct.
