Protecting buildings

[Bandit Mick]

Hello everyone in modelling land. Just a quick question that needs answering please.Whilst my shed is out of commission (AGAIN!!!!!!!!!!!!!!!) I thought I'd bring in my card buildings to 'preserve'. They have been weathered using black washes and weathering powders. Should I spray them to help preserve/protect them and if so, what should I use? Thank you in advance for your usual helpful advice.

PS When I told my doctor I did a bit of modelling in my spare time she looked a bit shocked! A further explanation put her mind at rest and I was allowed back into the surgery!

I ‘protected’ my card buildings by throwing them away and replacing with resin ones.
But card can be sealed with an artist’s matte varnish - I think Winsor & Newton make one. You may find it or something similar in the Range.
