As your car was previously registered to Seat UK, there’s s fair chance it was repaired in a Seat
dealership body
shop, rather than an independent Seat approved body
shop not connected to a
dealership, as Seat UK would have ready access to the
Seat dealer network facilities. From what I’ve read on various (mainly VW) forums,
repairs carried out by franchised
dealership body shops can sometimes be a bit hit and miss in terms of the quality of repair. Irrespective of whether it was repaired by a Seat
dealership body
shop or an independent Seat approved body
shop, there should be a record of the repair held on Seat’s on-line systems for the corrosion warranty to remain valid. I’d ask the
dealer you bought the car from to confirm this.
If you know someone with a paint depth gauge, it will be possible to measure the thickness of the paint on the wing which appears to have been repaired and also take paint thickness readings on other panels for comparison purposes. This will should confirm that the wing has been repainted.
I would certainly be discussing the undisclosed repair with the selling
dealer, bearing in mind you said in your first post in this thread that you asked about any accident damage when you bought the car and none was disclosed. I’d be aiming to get the
dealer to agree to the wing being repainted and the paint being blended into the adjoining panels at a Seat approved repairer of your choice at no cost to you, or at heavily discounted rates.
If you do get the wing repainted, be sure to check the quality of the work very carefully from different angles and lighting conditions for accurate colour match and finish, ensuring there’s no overspray on adjoining panels or trim and there no ‘hard’ lines where areas not to be painted have been masked off. Also, ensure you get something in writing to the effect that the repair has been carried out by an approved repairer to keep the corrosion warranty valid. If possible, take someone wth you to give an objective second opinion on the repair.
Good luck, please keep us updated with progress and the outcome.
