I am looking for info of which grease to use for bearings in a trailer.
According to a book on boat/trailer maintenance, the author suggests
using a white water proof grease for hand packing grease into bearing
because white color is easy for us to tell if we have packed grease in
all the rollers in the bearing (he suggests LubriMatic white lithium
waterproof grease). This sounds good. But it also says using a grease
gun to add grease into the Bearing Buddy type of greaser cap. I am a
bit confused. My questions a

- Is he talking about using the same white
waterproof grease for both packing bearing and
adding grease using a grease gun? If this is
the case, I should get the white waterproof
grease in a tube that I can put it in a grease
gun.

- Does he mean that if we use something like a
Bearing Buddy then we don't need to hand pack
grease into the bearing and we can simply use
a grease gun? In other words, I use either one
or the other, not both.

What's the real deal?
