My company makes link rods for the automotive industry and we're having problems with our ecoat painting on these link rods. We used to have problems with the paint "blistering" but that has diminished and now we're having a problem with the paint looking as though it builds up on the side of the part, making it have the pattern of tiger stripes. But its not down the entire part and its only on one side of the part. You can feel the defection with your finger and can only see it with good lighting. It also does not seem to be consistent with the direction and angle that the rods are placed on the racks before they're dipped.
Has anyone else ever come across this problem and what would be a good direction towards solving it?
