I was taking pictures the other night of an unfinished model airlane and found a flare that didn't come from the only light I was using! It appears to come from the white landig gear. I didn't know it was possible to get lens flare from flat white paint.

I would say it is more a reflection from your light source.Perhaps a bit overexposed to create the high key white spots.Or from your contrast in editing. Looks kind of real to me. Nice!

What I am seeing is not 'lens flare' it is 'fringing' - as doug has said it is caused by overexposure at that point. It occurs when there is an over exposed area next to a darker area in an image eg. shooting a tree against a bright sky you can often get a purple/blue fringe around the branches. It occurs most when there is a wide difference in the brightness and the exposure of the bright area is clipped by more than one stop. Most likely cause is voltage or light leak/bleed between individual sensor sites but manufacturers have spent a lot of money researching this and amending algorithms, sensor design to try and resolve the problem with so far only limited success. Difficult to do much about in this situation except to change the lighting.

Oops. Let me clear this up. This is film, and the flare is by the nose of the model.

Ahhh ok - I see it now. I missed that thinking it to be part of the planes paintwork.

Flares are caused by the reflection of bright things in your lens system. Whether that be an actual light source or the reflection of a bright object doesn't really matter. In effect the landing gear here is a light since the reflection of the light there illuminates part of the plane.
