I removed my spring, upper control arm, shock,etc... and was grinding away all of the gunk on and around the shock tower when out came a long strip of what looks like a beige seam sealer on the sides of the shock tower. This is on the inside of the tower, not the engine side. Has anyone encountered this before? What do I replace it with? It looks near impossible to use a caulking tube of sealer with the fenders on.
