Hey guys,
I´ve been using PM600 for years and recently a friend told me to try FETT2000, Motorex. After all, I dont have any experience with FETT2000.
Does anyone know both grease and could tell me which one is best? Does they have same use?
Thx, Regards

I don't know that drop point is all that important in MTB use, since we're talking about temperatures in excess of 140 Celcius before it happens.
PM600 is called "water-resistant," which means it is less suitable to water incursion. (Again, not a big deal in MTB, unless you ride through streams where the BB and axles are submerged.)
I think either grease is fine for MTB use.
I'll give fett2000 a shot anyway
In any case, to find out for sure, you need to try.
head down to the local boat store and get you some of that good good super waterproof marine grease. Works every time... nice thick red auto grease works wonders as well.
*unless suspension, use sram butter // slick honey
My personal favorite is BelRay Waterproof grease. Its thick and sticky and lasts damn near forever. Also good exp experience with Maxima waterproof. Lucas Red n Tacky. Dumonde MR grease for hub bearings, although it doesn't last as long. As others have said - slick honey for suspension and the lightest ever coating on shift cables. And of course, you have to keep around a small jar of your required hub mechanism grease (Dumonde Freehub say they are both DT Swiss and i9 approved - not sure a out King and others).
The loads also aren't really that high too. The grease is there mainly to prolong the bearing life by preventing water and crud ingress. That's what kills bearings on MTBs (and in fact most bearings in general).
I use FETT 2000 only because I bought it a while ago on Bike-Components together with my order, because I couldn't be arsed to look for something in different stores. I clicked and I bought it. When using it I generally coat the seams where water could otherwise get to the bearings, but I'm wondering if it makes sense as crud usually sticks to the grease then...
But yeah, if you have something waterproof to pack into pivot bearings (and headset), that's a good option. I'd keep away from it for the hub bearings though, they don't spin that fast, but still, it'd make sense for them to spin freely. And they're relatively well protected as they are also not in the line of fire of crud.
Always fully pack bearings with it and let them spin and wipe off excess.
Many brands carry the same gun, I just know Hazet has one (bought one at the same time as the Motorex gear that I wrote above). Works well.
As for bearings, fill them, spin them, fill them maybe some more and then squeeze the seals back on. There is no need to have any air inside a pivot bearing if you ask me. Though SKF Solid Oil bearings look nice for pivot applications.
Copper paste is a high temperature paste (usually used to prevent squealing of brake pads), that is used as a corrosion preventative. Plus it has copper particles, so it's not a lubricant per-se, at least not the kind you need in bearings and the like.
FETT2000 has been an experiment, since it is not that expensive here. So thats why I am trying it.
But when it becames to bike parts, prices are becoming a nightmare here.
Cheers
