Don't have a clue of what the doors are made of - but sounds like that old fashioned way to test if your car has had body work done. Run the magnet along the side, and if it doesn't stick - then Bondo's the culprit.

Yeah, your magnets SHOULD be sticking just fine. I've never had a problem.

No issues with magnets sticking here. The doors are made of steel, not aluminum or fiberglass. Sounds like there may be some filler in one of your doors from previous bodywork. I wouln't worry about it.

they stick on the trunks?
now that's weird because those are made of Alluminum and not steel like the doors and fender panels. Or maybe I'm confused..

You are. All the body panels, save the bumpers, are steel.

Same thing happened to me in my old 914. I went out for my first run as car number "32", and came back as number "3". One of the cone-chasers picked up the missing "2" on one of the corners, and returned it to me.

Bondo.

If i ever have to use magnetic numbers, im sure ill have that issue cause while the bodyshop guy pulled out as much door dings as he could.. he had to use alittle bondo here and there, I think you should make smaller numbers.

Did you ever do a PPI? if so did body work ever appear?

Try lightly tapping the area in question with a head of a screw driver and see if you hear a difference as you tap along the surface... if the noise echo becames more deep, then could be a spot of bondo in there.

That is indeed peculiar, I am quite sure my numbers will stick any where on the door, generally I place them right under the mirror. My numbers stick to the (rear) trunk lid, I keep the numbers on the underside of the trunk lid between events.
