Discovered bubbles on the roof rail trim today. Thank god the roof rail itself wasn’t rusting, just the trim. I park the car on an incline towards the front. So it’s a good idea to remove clean, Lanoguard and soak the screws in ACF50. Potential issue from rust in the future on the screw hole. Will ask the dealer to replace the trim under warranty. Why they put screw holes there I don’t know. Rear ones are completely clean.
