Craft help please ?

I want to do a Face-up on an Rainbow High Doll.

Every tutorial I have seen about #DoLl Face-ups uses Mr Super Clean Matt lear sealant spray to seal paint / watercolour to the face

I am in the UK and Mr Super Clear is relatively expensive to get here.

What alternatives can I use ?

[Thanks in Advance]
