How to 'seal' Autographs on a dashboard?

[Revolver]

Not sure where to put this? In the interior section? Car Care? Art section?? or Here? I placed it here because I think it's a general topic that some people have been faced with.

I guess that some of you are like me, & have your dashboard/other interior (or exterior) signed by your favorite driver/s in V8SC. Mine is on the dashboard of my fairlane. Now I got John Bowe's autograph months ago. & Craig Lowndes & Jamie Whincups the other week. Dad had his signed by CL a few years ago & it faded faster than a one hit wonder. My JB one is JUST starting to fade a little bit.

My cars dash sits in the sun, all day, everyday. & theres no undercover parking at either of my jobs. (well one has, but that runs by the offices, i.e, carparks have the office number they belong to). So how can I seal them from fading??? I have a art sealant that I sealed my drawing with, but I don't think it will work. Are there any products that can do this? or should I just use a sealer to stop them from rubbing off (even though no one touches the dash) & cover them up to prevent them from fading? Maybe a clear lacquer?

Any help would be great!
Cheers BBII.

P.S. The autographs are in a good quality permanent marker. Couldn't find a paint marker!
