Fluid film: I use it on my cars, works great where you are driving in salt 5 months per year. Smells like lanolin - which is what it is. If it's inside your frame I can't imagine you would ever smell it.
Boshield t9. Works very well also a good chain lube . no significant smell
frame saver. Have used it would rather use boshield as I have a gallon of it..... I'm set for life
