So, based on the polls and posts, it seems that the big debate is bike-specific vs. automotive vs. lithium greases. Of course, I browsed through the posts after trying my own idea:
Yes, there are precautions against mixing/blending different greases... But it just made sense that the white lithium grease seemed too "thin", while the automotive grease seemed too "thick", and mixed together they seemed just "right"...
I've already done it, it's already on the bike. However, has anyone ever done this and regretted it?
