Due to your comments, my dad saying "Eek! Don't do it" and a mate
saying "oh ohhhh" - I am going to live with what I have! A lick of
paint and leave as is.

TBH - work vs. reward isn't really going to pay back here. Rest of
house is the same artex - so it still looks like it fits.

The time is best spent doing the rest of the job properly.

Thanks!
