(((FIGHTING OOZE BETWEEN HEATBLOCK AND NOZZLE)))
I been fighting this ooze problem for some time. But, I also wanted to find something in my local store and not have to order online and wait for how ever long it was going to be delivered. I have came across some stuff called Megaloc.
Its a Multi-Purpose thread sealant. You can pick this up at a local Menards Hardware Store. I also use threading tape from Walmart. It feels like its more thicker than what you would get from Menards, Lowes, or Home depot.
Since I have used this product with threading tape I purchased from Walmart I have not even had a dribble of PLA from between heat block and nozzle. The threading tape also feels a little more thicker than blue eagle threading tape from Home Depot.
Now, I have not yet tried to just adding the Megaloc to the threads and run a print. I will give it a shot just adding Megaloc with no tape and see what kind of result occurs.
I also came across a tube of Harvey's TFE Paste. Not yet gave this stuff a shot, but I will later on in time.
Here are links to these products with info. I hope these help. I know I can walk away from a running printer with out having to get up and keeping cleaning ooze from between heat block and nozzle. Thank God.

Also here are some images on how I go about ooze prevention. Some steps are the same as what was given at the beginning of this post, but I don't think they add thread sealant to threading tape. I do that because of so many different ways of trying to stop it has stretched the nozzles just a bit, but not overly stretched. I have been able to let printer run for 48 hrs with out ooze and no strain on taking the nozzle back off the thread extension.
I hope this helps.
Steps.
1. Sorry no image of Threading Tape on extension threads. But I am sure you can imagine that procedure.
