FFCP: How to Glassbed, Hairspray and Bed leveling?

[SkyKisser]

Another newbie asking for help topic. Hope I don't hijack this box.
Hi guys
I see alot of ppl using glass bed and hairspraying suggesting leveling bed every pints. I don't mind leveling the bed everytime but not sure how to do it properly...note I have not upgraded a glass bed yet.
So you level the bed, take out the glass....put hairspray on it. Then put it back on and print or how do you pros do it?
I would prefer not to apply hairspray from the inside of my Flashforge Creator Pro. Is there away?
Thanks

I use hairspray on glass and only re-level if I'm doing a large print (> 2 hours) after removing the glass. Depending on models, I get about 6-8 prints before removing, cleaning and reapplication of hairspray.

You don't have to level the bed everytime, once every 3 times is what I follow.

You really don't want to be spraying hairspray into your machine, in fact I recommend you do it outside. There are alternatives to hairspray, personally I use PET tape on glass with a little ABS slurry. The hairspray smell give me a headache.
