I've been experimenting with the lucas red/tacky, it seems like a pretty durable grease, but during the summer months I have droplets of red liquid coming out of the gun hose nipple and t-handle.
It shoots out solid, I've been using it for about 2 years on a few friends cars (I still use the valvoline synpower, found a whole slew of it at a Napa in Oregon a few years ago, since kragen stopped sellng it, I"ll switch to mobil 1 when I'm all out)
So far the lucas seems to "work". haven't had to replace any balljoints yet.
