Proper care/preperation for "crumbly era" LEGO stickers?

[BraselC5048]

I'm rebuilding the 2002 UCS Naboo Starfighter, and I've got a brand new sticker sheet to replace the old crumbled away stickers. Before I put them on, I'm wondering about the best way to preserve them so they don't suffer the same fate as the previous ones. I've already scaned them as a .tiff at both 300 and 600 DPI. I've heard about Tamyla clearcoat, but since there's a ton of chrome on the model, I can't apply it after the stickers are applied. Does it work if I apply it to the sticker sheet before they are put on, (and would the stickers go on if I do that?), and is Tamyla clearcoat a good idea in the first place? I know exposure to UV light is the problem, but I also wan't to display it. One potential spot is in the northeast corner of a room with a single west facing window near the southwest corner. So far I haven't seen if direct sunlight goes that far into the room during the summer, but the blinds on the window are closed all the time anyway. Another posibility is on top of a tall dresser (2/3rds the height of the window) against the wall a few feet to the north of the window. Anybody know of any other tricks for making the stickers last?

I cover mine in a clear vinyl sticker. Might dull it a bit but seems to protect them well enough.

I've got the same problem with the 3451 Sopwith Camel (the first one). It bought it a few months ago second hand with a pristine sticker sheet. Now I don't dare to apply them, knowing what will become of them. I think that i'd better let someone make a set of copied stickers.

The only good trick I know to solve this problem is scanning them and then remaking them in vector format and printing them with a professional sticker printer on high quality (preferably the stuff used on cars two wrap them for promotional business purposes) material (vinyl). That is what we do at least. Costs quite a lot of time, but I think the only way to really solve this problem.

I just opened a 7470 Discovery Shuttle from around the same time period, and plan to tape over a few of them (which works well, but is time consuming) and just leave the rest of the sticker sheet. There isn't really a good way to prevent this otherwise. The stickers will break up even in a dim room, unless the room is completely dark. The only stickers that have remained in good shape for me (in the affected colors) are ones on the interiors of models.

Judging by your signiture, do you happen to be in the business of doing exactly that? It looks that way, and I know my way around image formats and scanning pretty well, but there's no way I could create a vector image, just at most a 900 DPI one.
