waxoil is you friend

I've used it for donkeys years.Squirt into seams first.Thin in cold weather & put two or more coats on.Mix with underseal for "wear" areas.

Ron there is another product worth a mention the body shops use it when they do a repair to doors or sills its called, Wurth Cavity Spray

It is very good for doors and sills - it is very thin and runs into the smallest of gaps
