Found some, actually a lot of sources for wintergreen oil and now I think I'm going to get some and see what it will do with the hood to air cleaner seal on my Air Grabber on my '69 GTX? It's kind of smashed and hardening and not sealing very well so I know I can find a container like a new plastic drain pan or similar low pan to soak it in and see what it will do?

Rubbing alcohol and wintergreen oil I'll let you know doc.
