I'm going to be purchasing a used 34k mile 2014 TDI R line. What are your thought on ceramic coats for used vehicles?
You can do that, but the benefits would be minimal to non-existent. Also, the wax would mostly mask the properties of the sealant (which could be beneficial in some regards, but will be just worse in most cases and aspects). Anyway, if you do top a SiO2 sealant with a wax, make sure to let the sealant cure first (at least a day) before applying the wax, because otherwise the solvents in the latter may interfere with the bonding process of the sealant, and you might even strip it off the surface completely. If you're using a cleaner wax, you'll do that (ie. strip any previous sealants) anyway, regardless of the cure time - so don't use cleaner waxes.Would you apply a wax after the sealant?
All the top of the line coatings (Gyeon, CQuartz, Opti-Coat, Ceramic Pro, etc) offer about the same thing, so it mostly comes down to personal preference - including which one's look you like best, and which one the shop you're trusting has the most experience with. Other than that go with the cheapest one - even though if you will also have a full paint correction done, the price difference should be negligible between them (because most of the costs will be due to the paint correction itself).I looking at a shop that is certified to use gyeon ceramic coatings. Any experience with that brand?
I suggest you look around for better prices. A $1200 charge should include at least a basic level of paint correction.shop around me charges minimum $1200 for the best Gyeon coating and that does not include paint correction. Does that seem about normal?
For one, that's impossible to say without knowing what the exact products are or what will be applied as part of the $1200 treatment. There's no rule that says that one can not charge $1200 and apply a DIY coating or something. Also, as explained above, most of the $1200 cost is from the labor cost of paint correction, not the cost of the actual coating product.Lets keep in mind the do-it-yourself ceramic kits are SIGNIFICANTLY different than the products you paid $1-2,000 to have applied.
Or not. For ex. CarPro claims that their DIY CQuartz layers "1-3 microns" thick, and their professional CQuartz Finest "3+ microns". Which is in essence a nice way to say that there's no distinct difference in between the layering thickness of these products. Even if there was, CQuartz is also layerable, so, one can reach even 6 or 10 microns thickness with it, if they wanted. That said creating a coat thicker than 2-3 microns rarely (if ever) makes sense, because it will not enhance neither the look of the car, nor the gracefulness or speed of the paint degradation. It's essentially just a waste of money, product and labor, for the sake of itself.The expensive professional products are several microns thicker once applied than the DIY kits.
They cost the same and they deliver about the same. The differentiation between the DIY and Pro product lines are in reality more about market segmentation and upselling (ie. letting the rich - and/or dumb - people pay a LOT more for mostly the same stuff), and about providing a high-level all-round service, than about the product being really that much different, or costing more (in terms of material/production costs).That doesn't mean the DIY kits are bad, they aren't, they just aren't in the same class.
