However, a while back Nu-Finish was used in one-pass lubrication/protection when trying to
extract music/sound off a deteriorating R2R (and the occasional cassette tape)
but see tapeheads for the latest in case you move it from the garage to the audio system.
I've used primarily Meguiar's for years myself. Lately it's been the 105 and 205 compounds, plus #26 Yellow Wax. I use an orbital buffer to do the work, except in the rare instance something is really wrong and I have to get out a rotary buffer to correct it. Sounds like Nu Finish is more for older vehicles prior to clearcoating.
