Nice video. Question: What sort of grease "run-out" around your "seals" do you find? Is it immediate, or after how long? Have you tried different greases? Thank you.
The main reason the grease leaked out was if too much was put in to start with. I would recommend not packing it tight with grease and the sealant should do it's job. Remember it can still come out of the shafts if over-filled. I did try marine grease which is water-proof and this worked well.
