thanks to all who answered part of my question-I’m just also wondering how important it is to clean off the old dried up glue, or sticky foam, or whatever’s on the back of the wood and also the metal areas on the dash. If it doesn’t matter, fine, but if it does, what’s the best way to do it? I’m thinking some type of solvent with a scotch-brite pad or something..but maybe that’s a bad idea (?). What solvent would be safe and not dissolve the finish on the face of the wood trim?
