How do you seal airbrush acrylic paint?

[VIARPE]

Hello everyone.
I started airbrushing my costume parts a few days ago.
Airbrush paint is very sofly coated, and if I scratch it with my fingernail it will get scratched...
What do you use as final layer coating to avoid paint to peel out? any matt varsnish?
Thank you!

Vicente.

1st, let it dry for a few days until the paint fully hardens. Then use a matte clear coat. I use Testors or Model Masters spray can, found at hobby stores or amazon. It is not scratch resistant, but it should help. Do not use the Rustoluem found at Home Depot or Lowes, it is crap

Good advice from Tfett40. The Testors (or Model Master) clear sprays are lacquers and give a pretty rugged finish.
Make sure not to spray it on too heavy though. A couple of light/medium coats will work much better than one heavy coat.
If you lay it down to heavy it can actually melt your underlying paint. . . ask me how I know.
