Working on restoring a set of tail lights for my Corona. Everything is complete, but the seal between the lens and the housing is perished and chipping off. What is my best course of action here? Leaving it as is, stripping it out and leaving it as is, or creating a new seal with caulking. If it's the last option, what kind of caulking will do the job of sealing without permanently binding or otherwise altering the pieces?
