I replaced inner fenders on my 69 dart, should i seam seal the overlap joint by the firewall? I am just not sure what the correct way is, they were pretty cut up before so i have nothing to go off from.
I don't think the factory put seal sealer there. It is a tightly closed overlap with a heck of a lot of spot welds. Sealant normally goes where a leak isn't wanted. A small leak through that overlap wouldn't matter.
