Increasing Adhesion PLA & PETG on Spring steel sheet (Smooth PEI)

Hi,

I'm most familiar with printing on Mirror with gluestick, hairspray, or blue tape.

The main issue I've had so far is parts detaching prematurely from the Spring steel sheet with smooth double-sided PEI on the Mk3. Even with a minor brim, some parts are a challenge to stay stuck.

I typically use glue stick, and my first layers look fantastic (Love that PINDA!).

I see mention of gluestick, and ABS juice, but no mention of Aquanet, Magigoop, or other things to make it more sticky.

Is it OK to use hairspray on the PEI?

What about other adhesives like magigoop?

Answer this question I have this problem too

Is this a good question?
