I've never heard of this. Do you just coat the outside or do the inside of the nozzle as well? Also is there a brand your recommended?

[@SliceEngineering]

We recommend coating the outside of your nozzle, as well as your hot block or silicone boot too! We sell our own PRP that we make, bottle, and ship from right here in the USA!

I found the web page! One thing I don't see and might have missed, how often do you apply? Every print? Every 2-5 prints? Whenever you notice it's sticking again? And do you just apply over it or do you need to clean the nozzle first?

[@SliceEngineering]

Great question! We cover this in the full video on our channel, but there's really no good general recommendation as it varies by printer, usage, and material. Our recommendation is to just reapply whenever you start to see a little more sticking than normal. A little PRP goes a long way, so there's no harm in applying a light touch up coat just in case.
And yes, you can just reapply over a previous coating of PRP, but if your nozzle is dirty you'll want to clean it first for best results. Hope this helps!
