Grease for Poly Bushings?

I installed Polyurethane Bushings in my control arms, and drilled and tapped them with zerks fittings. I have been using plain old chassis grease. Is there something more correct that I should use?

I like a calcium sulfonate thickened (marine) grease as it resists water washout better than most chassis greases which are usually Li or Li complex.

Is the polyurethane compatible with the lithium complex thickener??

You can buy it in cartridge form for your grease gun

This, and some use the Super Lube synthetic clear stuff as well (it's actually recommended by UMI (performance suspension component company) for use in it's Roto-Joint control arm/panhard/a arm/etc. ends with poly or delrin bushings.

But, the Prothane/Energy Suspensions products are MUCH thicker/tackier, and WILL outlast the Super Lube like 10 to 1.
