Thread: Adhesive for door patches

Tweet

not sure if anyone mentioned it but when your doing patches with metal bonding adhesives they have been known to create a shadow effect when painted that will show right through your primers sealers and paint. when i was in school they had said metal bond was acctually stronger than welding. when put to the test the metal tore before the glue gave way. i did however weld patches in on my doors.

Usually because there wasn't a large enough area for the glue, needs at least 1" wide flange for the patch or panel to sit on.--when done this way, no shadow or ghost line....
