I used tufshine on my tires way back before my mustang. From what I remember it is pretty good stuff, probably better than the Ultima I'm using. I'd definitely prep before the Sonax as well. How is UK at holding dust off? Literally one of my biggest pet peeves is to come out after work to my freshly waxed car, see the dust on my car, attempt to blow it off with a spirited drive, only for it to stubbornly remain there.
I guess my only concern would be that my FK 425 would mask properties of the SPNS. I still have about 1/2 gallon of the stuff and don't want to waste it. The BSD from what I understand is a quick detailed but also boosts the properties of SPNS correct?
I doubt FK425 will mask the properties, SPNS has a rubbery feel to it, actually repels dust quite well. BSD is some thick stuff, its not something I would apply even with light dust - really just personal preference cuz of my OCD with black paint lol. As for UK, it helps a lot but then again my stang is black, so no what what I do, I attract dust. The recommended combo is UK/Reload...
