Well, I didn't like this reply I just got...

***Hey Andy,
No we do not offer a protective coating.
Once your side art is applied it is to be handled with care.
This is solvent print without laminate.
You can add one yourself after you apply the artwork but it's only bit more durable.
When it comes to the pinball side art I do not know
Thanks again and Game ON!

Handled with care!!! My brother refurbished a few pinballs over the last couple years and the most recent one he go artwork with no protective coating... his watch just brushed up against it and put scratches on it... and while do some final things he accidentally got a few drops of rubbing alcohol on it and it took the ink off. He ended up totally replacing it.
Anyone know of anywhere else I can get artwork for a cockpit Spy Hunter?
