    I am trying to understand some facts in this world of marketing hype. Here's my question / thought:
    Assuming I am after making my car as "hydrophobic" as possible because I want to make washing and drying as simple as possible. So, I have been reading (and reading and reading) and realized that all the "best" ceramic (nano or whatever) coatings need to be "reloaded" or "topped" to maintain the best water effects or hydrophobic-Ness. The coating lasts a long time, but it sounds like the first thing to go is the hydrophobic nature. So thinking about it if all these coatings need a sealant or topper to maintain the best hydrophobic effect, could I just add the sealant to my synthetic wax? If my goal is just hydrophobic effect, why can't I just just add that? Also, the logical follow up question is what is the most hydrophobic sealant /topper? Exo?
    Thoughts?

    If you are only after the hydrophobic properties, you could just apply a sealant to your car every 4 to 6 months. Personally, I put a sealant (Carpro Hydro2) over ppf on my M3. It's been a month and a half and still looks really shiny and still has the hydrophobic properties. The sealant gives the car a nice shine and hydrophobic properties, but it's much cheaper and super easy to apply.

    This site has some good info on the differences:

    How often do you have to redo the sealant? Did you immediately apply this sealant after your first wash of your m3? Curious because I'm planning to hand wash my m3 when I get this Sunday but not sure when I should apply a new sealant on it

    Sealant or top coat should be applicable whenever the car is clean.. .

    Sorry i may have asked my question vaguely, i meant although we can put on sealant everytime, how long does the sealant last so I wont have to do it every car wash? Or will it come off after every wash?

    there are spray on ceramic coatings that claim to last 3-6 months. never tried using one yet though.

    wax would go on top of the coating but id say theres really no point of wax if youre coating the car

    Primer goes on to protect the metal.
    Color coat goes on to protect the primer.
    Clear coat goes on to protect the color coat.
    Plastic film goes on to protect the clear coat.
    Wax or ceramic coating goes on to protect the plastic protection.
    Ceramic enhancement goes on to renew the ceramic coats water shedding properities.

    Seems like it never ends, but there is great pride in driving a clean and shiney vehicle

    It will probably depend on the product. The one I used (hydro2) claims to last up to 3 months, although I’ve seen some people claim it lasts 4 to 6 months for them. You do not need to reapply every car wash. I don’t know all of the chemistry theory behind it, but it is made with SiO2, which is what glass/quartz is made of: Silicon dioxide - Wikipedia

    In the world of nanocoatings, Modesta is regarded as the best for black cars. It’s thicker, takes longer, and has a longer warranty (10 years).

    Opti-Coat in my mind ranks second, C-Quartz after that, and the list goes on. artsci’s testing of Permanon should be required reading.

    Putting a nanocoating on top of a wrap is in my mind overkill.

    Rest assured that each statement above will be contested. Welcome to the religion and politics of aftermarket care.

    For hydrophobic properties, Optimum’s No Rinse Blue (no wax) is great but it won’t last much past the next car wash. On the other end of the curve would be one of the coatings referenced above, but here’s the kicker - and upon this point I would think there would be near consensus:

    No matter what you do, if you don’t reapply something annually or quarterly (Opti-Seal, more Permanon, carnauba wax) or as part of every wash (depending upon what you’re starting with), and if you don’t decontaminate your car once in awhile to get all the crud out, optimum hydrophobia will not be yours.

    I have a friend who owns 7 black cars. He pays someone to wax them every 3 months and otherwise runs them through whatever car wash he drives by. That’s it, and he’s happy as a clam. You can see swirls all day long. Doesn’t matter one bit to him.

    Then you have absolutely gorgeous examples of mirror-like glossiness (see the artsci thread referenced above and numerous others).

    Hydrophobic surface prep is easy. Getting and keeping that glossy perfection? Heh. Enter the matrix of skills and time.

    Awesome, this is what I was looking for! Good to know and I'll for sure be getting the sealant your recommended.

    Why go with wax in the first place if you're going to have to keep reapplying it constantly to maintain the gloss?

    The only real advantage of wax has over ceramic is if you get a scratch in the clear coat you don't have to take down all the ceramic coating to level the clear coat.

    The silica sealant doesn't have to be reapplied that often. It depends on how often you wash your car.


    CQuartz seems to have the best gloss and the hydrophobic effects last the longest.
