Can this be applied over PEI? I have an old Prusa Mk3 PEI spring steel sheet with smooth PEI that I would like to use but don't want to remove the PEI film if possible.

Can you print pla without glue on this surface?

Not a question: I just wanted to say that this garolite sheet is awesome. I've been printing on PEI exclusively pretty much ever since I got my printer 9 months ago. I recently started printing PETG and decided to see if there was any other build surface that would have the same amount of adhesion without taking a part of the surface with it when I removed the part. This stuff fits the bill perfectly. Just as good adhesion as PEI with an easier ability to remove the part with the plus that the bottom surface is shiny like glass rather than matte like PEI. Stick this onto the bottom of a flexplate and you'll never look back!

Can an Ultimaker S7 Sheet be added? Or should the S5 details be updated to include the S7? Is it also compatible? Also, it states that glass is required for the thin sheet and not required for the thick sheet. I have a metal flex plate included with the S7, so which would be needed?

There was an error with the Z access and the nozzle slightly dug into the printbed (Id say maybe .05mm into the bed or pressure on the bed) leaving a trace and a lighter shade/white residue almost on the bed and I fear may be permanent damage any suggestions on restoring/cleaning the bed? (Was printing with PLA Ex-205 Bed-75 )

How well does this keep its form? I mean does it warp easily? I bought gasoline just like this from ebay that was half inch thick and that thing worped in the middle like crazy once it got heated.

When applied to the glass, does this material work with Ultimaker S5 auto-leveling or do you have to switch to manual leveling? I intend to have two glass plates to switch between... one with PEI and one with this Garolite but I want to retain auto-leveling if possible, to avoid having to swap between different startup G-code sequences, etc. Thanks!
