Let me be the first to say that I think you stole a minty HUO SoF Congrats on the find!

I need to do something similar on my SoF. The original silkscreened ink over the inserts was worn down and the previous owner placed decals over top of those partly-worn-down graphics. This was done without lining them up very well, in some cases.

I'd like to strip the tops of the inserts down to bare plastic and add new decals. Is it possible to do this without removing the inserts from the playfield and sanding them, etc.?

Peeling up the old decals won't be too bad, I think. Would you use something like a flat xacto blade to gently scrape off the old ink underneath? Or is there a better method?

Agreed, lionman callout and flipper 'thwack' 'thwack' can get old, but otherwise the soundtrack is killer. Love the high score music!
