In experiments with covers, to detach the corners in Hanxi, I began to take off - cracked. The glue is not rubbed, but subjectively wukong seemed stronger.
Yesterday pasted wukong full cover, cover Valid almost complete, even with Supcase style does not seem friendly at the corners.
Oleofobka worse than the Hanxi, but not significantly, image distortion is not noticed. Anyway, all loca-glasses that pasted, oleofobka much better than glasses coated with glue that was holding. Carefully examined wukong case fr. - identical.
You may be out of luck with the adhesive, it is cloudy or yellow, I glued on tp2500f.
