Fixing/Stabilizing Acrylic Paint Artwork

[Jennison]

I’ve got an A-2 with a painted wings & star emblem on the shoulder. It was done back in 1987 and has held up pretty well; I’m assuming it was done with acrylic paint. However, there are nicks in the paint (see photo) and I’d like to keep those from becoming problem areas. I came across this “acrylic finisher” stuff and would like to know if this would be a good choice to seal the nicks. I’d be dabbing pinhead sized amounts right in the tiny voids. If this stuff isn’t the ticket, what should I use?

I'm using the same thing to seal the paint on my patches.
Works fine and looks like it's holding up quite good.

Fishing's Resolene is another clear finish...

PVA glue / sealer will seal as well, dilute to taste.

Acrylic clear floor polish (called Future in the States and was called Klear in the Commonwealth but not available now sadly although alternatives exist) is perfect. It's exceedingly hardwearing (hardly surprising it's designed for people to traipse up and down in shoes thousands of times) and also flexible.

Created my own shellac laquer, mixed with natural dyes and veg. oils…. Using it for restoration.
Once dry… even in a shower bath it will not
dissolve..
