The Cosmoline is less sticky with time, I doubt it will need any coating to keep it looking good with fair weather cruising. The lower bushings are Hotchkiss regreasables (they don't look 100% correct but I'm gonna drive the car so I made a functional judgment call). I also dipped the correctly dated originals with OEM style bushings in case I ever want to swap back (huge PIA though). I bought the Cosmoline online direct from Cosmoline, it was around $400.00 shipped for 5 gals.
