Finishing with Armor-All???

OK… I’ve never tried this, (scared to death to)... but I read this in FWW’s Proven Shop Tips (pp44). For woods like purpleheart and padauk you can apply Armor-All a few times before the finish to keep it from changing it’s color and darkening due to the ultraviolet light. The writer of the tip suggests three to four applications, and then use an oil finish, which is compatible with Armor-All. He continues to write that other finishes like lacquer or varnish may not be.

Has anyone ever heard of or tried this? Are there other finishes that would protect the color of these woods that you have tried? Just curious.
