Sanding may be an option, never tried it. My last decal removal, the decal and glue pretty much came off in one. I didn't know the P2000 decal  application is different. The decals don't have adhesive on them. The actualy glue is applied to the cabinet. Whereas my replacements have the glue on the decal.

Any suggestions greatly appreciated as I've only done the RHS headbox to see what I'm up against.

Another thought I am considering is leaving the glue and applying the decals via wet method as I noticed the glue on the cabinet is somewhat uniform even after decal removal. I just don't know if spots that may not have any glue will show up on the decal once in place.

BTW my cabinet seems in real nice condition and the decals had scratches rather than deep gouges so no bogging required. I could have probably left the decals as is but I'm fussy to the extreme
