Going to stop updating until its done. Needs ten hours plus I reckon. Had two hours tonight on a 50/50 mix. I'm feeding it through the bottom bracket shell using an old pump. Top of the seat tube is bunged up with one new pack of blue tac, working a treat.
Fumes!
Lots of black silver froth, doing something at least
Now onto fifth bottle of caustic soda... But nearly there, post has broken down and dissolved completely In a few patches but not given up in full so going to need to do it some more til it all goes. Bloody long time doing this!
