But I have also found that if the finish is cared for, it really takes a minimal amount of time to put on a fresh coat in a month or two. As others mentioned, I would do some research on some of these ceramic coatings on the market.
I have never gotten good longevity from Meguiar's waxes (not counting their new ceramics, I haven't tried those yet). The longest lasting waxes I've used have been what many people call the "boutique" waxes, such as Collinite, Zaino, Duragloss, Klasse, etc. Also, the type of wash solution has a lot to do with how long a wax will last. Most, if not all car wash solutions should not remove the wax. Some even build on it. Of course, time will remove any wax/sealant, but the proper wash solution should not.
Thanks for your honesty as I have had the same experience even with Meguiars Ultimate Wax which is synthetic. I remember reading somewhere that all carnauba based waxes break down in intense heat such as FL and do not last although they look great at the start. That's how I learned about the Finish Kare FK1000 as it is a high temp synthetic wax that doesn't break down and last quite long on a vehicle stored outside in FL. ANYTHING will last for sometime when the vehicle is garaged at which point it comes down to more of personal preference as to how well it looks.
I've also heard the FK 1000 is long lasting, though I've never tried it...
