If anything I am more concerned about the seat post grease/lube/thingy because I hear they can fuze together if not greased/lubed

In regards to the degreaser, I used simple green and noticed some damage as it took some coating off and now that part has spots on it

I just want to know where I should inject grease in?

I was considering this...
