The face plate on the radio is not great. After a year or two of intensive
use some of the numbers and letter were wearing off or chipping. It's not a
huge
thing but for the money a protective coating on the face plate would be
worth
it.

If you're buying a refurbished model, which has already been opened up to
fix/improve/what have you, you may feel comfortable buying a tiny bottle of
clear enamel and lightly *brushing* it over the words and numbers to seal them.
I do not know if the face of the Sat800 is glossy or satiny or flat in 'sheen',
so get a clear coat which will match the factory finish. Do NOT use clear nail
polish, as it is only gloss in finish and if it doesn't eat into the faceplate,
will still crack off easily after being rubbed or pushed for a short time.
Plus, a small bottle of basic clear enamel will come in different finishes to
match the radio, and when purchased from a hobby shop will likely cost you less
than anything you can find at a nail boutique or even the cosmetics dept. at
your local department store. I've used this method to seal decals for crystal
sets, restored vintage sets, and other projects, and have yet to have anything
go wrong. If you use a light enough coat, no one can tell, even you.
