Sealing old decals?

[Plowboy]

I'm building this kit.

Needless to say, these are some pretty old decals. I have two sets. But, they're a shade or two different from each other. Do these need to be sealed if they aren't cracked? If so, with what?

I seal all my decals no mater how old they are you can use testors clear or tamiya whatever works best for you. Plus what I do is scan them before I use them just incase

It wouldn't be a bad idea at all. I like Micro Superfilm.

MPC decals from that era will definitely need to be sealed!

Thanx for the info! I'll use Tamiya since that's what I'll be using over the paint also.
