I've got a TSPP that looks like it spent most of it's life in an ashtray in a cigar lounge. I'm trying to prepare the cabinet surfaces for the new decals I've purchased and have a few questions about surface prep.
I've used a heat gun to remove the old decals from the cabinet, which has left me a mostly smooth, non sticky surface. I gave the surface a wipe down with Goo Gone, and don't feel any sticky residue. It does seem like there's something still there, however, just from looking at it.
Should I sand this surface, or do anything additional before applying the graphics? I've seen videos online about removing graphics which has left a glue residue, but these have all been Williams cabinets so I am curious if I should expect a different process with a Stern cabinet since I don't see or feel any glue residue.
Thanks for the advice.
