Quoted from FYMF:You can replace decals. You cant send your machine back to the printer when someone's scratches it badly.
A ring or watch could mess the clear coat which can be fixed but I'd never route them.
In fact, one of the first things KT said to me which instantly told me I was dealing with a great family and company: I told her I wanted butter and she asked if HUO or route. When I asked why she asked... she explained that if they get gouged, you're not going to be able to fix it as opposed to her going for the $1000 upsale.
My understanding was that Spooky really doesn't profit from the butter cabs, they just pass along their added expenses for producing a butter cab. Regardless, Spooky is always looking out for their customer's best interests.
