Hello,
I am looking to make a PTFE coating to apply to plastics, glass or acrylic plates/boxes. The purpose is to prevent insects from crawling over them, so as an escape prevention.
I have been looking around on the internet for this and have 2 questions:

Firstly, will any type of PTFE coating (commercially available) be suitable for this? I'm not certain "greasy" coatings will work and am also not certain if they will be easy to apply to the surfaces I mentioned. If so, feel free to make suggestions.

Secondly, I have found a pet shop selling "fluon", which just looks like a watery suspension of PTFE. Can I just disperse PTFE powder in water and apply it this way or do I need to add additives (I've heard mention of soap)? Is there also a shelf-life to take into account for a solution like this? What would be a good concentration if this is possible?

I have no experience at all with this, so let me know if something is unclear or if you need more information. Thank you.
