Don't know if seam sealer is used or not, but here's a tip, make some washers out of old plastic milk jug or laundry bottle material. Install these with a few of the fender bolts for the line-up process. Remove the washers and reinstall the bolts when everthing is just so...you'll save scratching the finish with the external star washers.
