ok guys, i know someone who told me that its better to apply the sealant last over the carnuba. i told him that the other way around is better, apply the sealant first and then the carnuba.

for example, i have 4star UPP and s100 paste wax. normally i would apply the UPP, wait 24hours, and then apply the s100.

i recently got into detailing and i havent had enough knowledge to explain this to that someone so he can shut the **** up.

if im right, can you guys explain to me why applying sealant before carnuba is better. thanks for the input!!! remember, that someone jerk told me that carnuba should be first and sealant last.
 
You have it right, the sealant goes on first then the carnuba topper.
UPP is a sealant and is going through a different process than the carnuba.

Sealants are "bonding to" the surface through a chemical process (I'm sure someone here with greater chemical knowledge could explain better) The Carnuba is "curing on" the surface as the carriers and solvents dissipate.

The sealant needs an extremely clean suface to bond to.

The difference between a sealant and a wax is like the difference between super glue and elmer's glue on your skin. If you put elmer's glue all over you hand it will stick, but if you move your hand around the glue will loosen from the skin, the same thing happens with a wax. If you put super glue on your skin it will stay there until you remove it either chemically :flamed or mechanically :wall . The super glue makes a molecular bond to your skin. Sealants do the same thing. This is where the bonding issues occur, if you put wax on and then add a sealant the sealant will bond to the wax layer and not the paint. This will actually make the wax have less life because it it's now about twice the weight (think of water beads on your hood, the little don't fall off, the big ones do).
 
Bonding- James 008 Bonding

Bonding:
1.Carnauba wax will bond to a cross-linked polymer; conversely if a polymer is applied on top of Carnauba wax the cross-linking / bonding may be compromised. Although I would not state categorically that a product that is formulated with oils will abort the cross-linking or bonding process of a polymer just that the process may not be as complete, and its strength and durability may be affected

2.You cannot apply a polymer over a Glaze or a Carnauba wax due to bonding incompatibility

3.A polish that contains oils should be cleaned with a 1:1 solution of Isopropyl alcohol / distilled water before the application of a polymer (See also cross-linking and Set-up Process)
