yup... water can get into the Retro Encabulator AND effect the inverse current of the Magneto Reluctor and rust the Prefabulated Amulite YOU ARE SCREWED!!!!!!

So I just realized my car doesn't have the gasket around the attenna so their is an exposed area. Am I screwed? It's been raining the past few days and I can only think the worse case scenario which is water getting into a 20 year old chassis and eat it from the inside out.
