PRESSING Glow and Holo Covers 0

[Sahbatage]

I've looked online to find a slew or answers ranging from "It will ruin the cover" to "it can be done with extra care". 

Can I press a glow in the dark and hologram cover?  Is it not recommended?

I want to send two of my books in for grading (Return of Wolverine 1 Glow in the Dark Variant and Wolverine 75).  Neither are expensive books but will be added to my wolverine display which is all 9.8s.  Dont want either book being the odd 9.6 or lower duck haha.

Thanks in advance!
