Liquid Gold has a kerosene-like petroleum base and that would cause laquer not to stick. It would be excellent to get the smokey, oily, brown, coating off though. Mine looked as though it had a 3 pack a day habbit. I finally used Dow Scrubbing bubbles, not pressing on the decals. It worked well and didn't damage anything, but I put it on the cloth, not the machine. I then used "Back to Black" (WalMart) car polish and now it sparkles like a new one. Don't ever spray anything on a machine, only on the cloth to prevent wetting something you can't get dry in the cracks. I hesitate to clear coat them because they really need to be taken apart to do a good job after they were deglazed. Maybe someday. I really enjoy Charlee's posts. She really knows her stuff.
