Tubular UCA install questions

You did grease them, right? Urethane takes some special grease too.....I forget what it's called.
My poly bushings came with a white silicone based grease that really adheres to the bushing and is impervious to water & oils. Like the old commercial "a little dab will do 'ya" when assembling. I used a moly based grease in my grease gun.
