Think of a that washing up advert when the plate squeaks when you rub your finger down it.
The plate squeaks because the surface has lubrication (water) to slide over, but so clean that your finger snags and jumps on the surface.
You need the seals to snag on the painted surface, any movement in the shut lines are absorbed by the hollow seals changing shape because they are snagged to the painted surface, without the snagging the seals slide over the surface creating the squeaks.
intriguing...why then does it get worse in summer when the rubber is more soft?
