What your talking about is beyond my understanding. PTFE is not thin oil for your single cylinder. You spray PTFE, then wipe it away and there is very thin layer of Teflon is on surface. There is nothing than could collect dust. At least Breakfree CLP is one of a few oils than could work at extremely low temperatures, 'cause actually there is no oil that could freeze, but very thin layer of Teflon again.
Plz don't disturb anyone with your not smart notes anymore.
