PTFE coating doable at home?
(OP)
I cant seem to find much info regarding home-brew teflon coating which I figure means it probably wont be easy at least. This would be a damn handy this if it could be done. Can anyone shed any light on the process/equipment required? I have high vacuum if that helps...

I have the details on file, but not at hand.
DuPont may still publish a manual or technical bulletin, but convincing them to give you one for home application might be a challenge.
It is difficult to control the process and involves strong corrosive chemicals, high heat and surgcal levels of cleanliness. The problem is that PTFE releases just as well from aluminium as it does from any other surface unless you can create strong mechanical key with undercuts to lock the coating to the metal.

To your question of application methods - there are many methods as there are many types of surfaces and reasons for coating. Coating fabrics is different than metal surfaces.

Aluminium saucepans are on sale everywhere - I even have some.
PTFE is only put on Al to stop your fried eggs sticking to the pan...

PTFE will not be a good choice for that application as it is porous and you will get corrosion of the aluminium underneath.
Unless the system is pressurised, at 100 deg C you will get cavitation and consequential erosion of the pump components.
I would also be investigating food grade epoxy coatings. The only qualifier is, I am not sure how good epoxy is to hydrolysis at 100 deg C.
If applied correctly and maintained correctly, PTFE is by far the best non stick surface. I do have substantial data to back that up.

From what I have learned so far it doesn't sound too far out of reach ie, chemicals,careful surface prep,fumes,high heat.
