I use the Standard Vantagloss, & it is awesome. A slightly cheaper alternative, that works like crazy, is their Shine On.
Only problem is, I ordered my dam Ryko SoftGloss w/ Blue LED Lava Wax. Why? Cause Quest had Blue Shine On, & it really popped. 18 mos later & they only offer Shine On in Yellow!



They also changed the fragrance from Vanilla Dreamsicle, to Grapefruit. Smells good, but not awesome, like before.
Quest is great, but they experiment too dadgum much.
Quest Triple Foams are rhe bomb! I have used low ph & their polish & both are A+!!!
What's other guys experience with Quest best high ph PreSoak, for IBA's?
