I have experience with the gwr products.
The Ceramlube is supposedly the same product as the Bendix Ceramlube. In my Caravan, as The Critic said, it dried out in my pins, gummed up, and resulted in poor movement. At least one other member here said it worked good for them.
The Stalube is a high solids moly paste that I imagine is similar to the Molykote M77. The Stalube is extremely water proof. I use it for the exterior metal to metal contact points.
I went back to using Sil Glyde, an old time product that I believe contains very little silicon, but seems to work. I also have used the Motorcraft silicon with success.
My trials with the new fangled synthetics was a bust. The green Permatex also dried out in my Caravan.
