Re: Buying used Prusa MK3

Re: Powdercoated PEI Sheet Surface Prep

Hi Randy,

for TPU and PETG, windex should do the job,
Alternatives,
1, Talcum Powder, rubbed well in and surplus removed.
2, Finger grease/ forehead grease, rubbed well in..
3, Gluestick, rubbed in with moist cloth to prevent clumping, and visible streaks.

regards Joan
