Accidental glue stain

Hello, I am modeling the Walthers ICE HOUSE and I accidently touched the roof (shiny black) with the glue brush.

Now this left a glue stain and I would like to know if there’s a way to remove this “glue stain” or to camouflage it.

My initial intentions were to apply several coats of gray pastel chalk to give it a more metallised look.

Any suggestions are more than welcome, I don’t want to “trash” the model just because of a glue stain.

Thank you.

If the roof is shiny black paint over it with some shiny black paint. If it damaged any detail make it look like a repair crew is fixing it or somebody has come along and done a quick patch job on it.

I dont sweat the glue marks or CA vapor stains, a little weathering paint and some dullcote and all is good.

Thank you for the infos.
