In the process of replacing rusted panels in the engine bay I found where seams were covered with a kind of "stuff" to seal the joints I guess. In some cases I've even found what looks like chewing gum in various holes. Does anyone know what this sealant is called and where I get some to finish out my patches?
seam sealer can be bought in an auto paint shop in tubes like silicone. You just run a bead of it where you want to seal it, and it hardens overnite and is paintable. Its also called Drip Check Sealer (because it was also used on roofs where the drip rail was). Most cars now dont have a drip rail...so when you open a door in the rain, all the water will run in.
