Bit of play on words, but I have a question, sparked by videos from Todd C from Esoteric Car Care. On COATED cars, he advises using a coating topper as a maintenance product - Overcoat, Polish Angel, Cure etc, but strongly advises to stay away from using quick detailers, shampoos with gloss enhancers/waxes, spray waxes, paste waxes for maintenance. Essentially, he says that you are obscuring/limiting the benefits of the coating and replacing it with a lessor product.
Thoughts?
I think the above is kinda a multi-faceted question, the first being their philosophy regarding the use of any Quick Detailer for light cleanup and the second being topping coatings with `non coating-synergistic` products like traditional waxes, sealants and shampoos with polymer gloss enhancers.
In the first case they seem to eschew the use of any Quick Detailers (both ceramic and polymer-infused) for light cleanup due to possible marring of the surface. Kinda a "Live with the light dust/dirt until full bucket wash is possible" approach, akin to many opinions regarding light cleanup using a California Car Duster.
The second scenario is the generally accepted philosophy that putting a non-ceramic on top of a coating masks the benefits of the coating with regards to water behavior and such. There`s some folks over in the Corvette World that just adore Beadmaker so they use that stuff on top of their coatings...and then note that the beading, sheeting has diminished and dust attraction has increased vs the coating alone or the coating with a ceramic-infused maintenance product.
As far as using toppers/boosters, dunno, but perhaps…
1. The elements that provide the durability and chemical/environmental protection of a base coating do not provide/are not compatible with the more entertaining aspects folks associate with a ‘good’ LSP.
Things like slickness, exciting water behavior, beading, added gloss. In other words, the base coating provides the functional aspects, the booster the aesthetic aspects. Gyeon Mohs, Gtechniq CSL for example are some pretty tough customers but the visible water behavior is visually not that entertaining, hence the Skin topcoat in the Mohs-based Syncro kit and the ‘preferred’ CSL +EXOV4 application combo.
On their own, Mohs and CSL are more hydrophillic as opposed to hydrophobic and that’s just not as visually entertaining as when topped with a more hydrophobic top layer. While Skin and EXO are ‘kinda coatings’ like CarPro Gliss, Feynlab Topcoat and TAC Topcoat, the concept of topping a coating via dedicated ‘topcoat’ or booster is, to me, kinda the same. The base coating, for whatever reason, can’t encompass all characteristics people recognize as ‘quality’ behavior of an LSP.
2. Sacrificial layer or protecting the protection. Better to contaminate a top layer than the more expensive base coating.
3. Revenue generation. More products needed to maintain the base coating benefits, real or perceived. “You spent all this money on getting it coated, what’s a little bit more?” Kinda akin to changing oil every 3500 miles instead of following mfg recommendations of up to 10k intervals. Better safe than sorry?
4. Just following directions. Most mfgs reccomend some kinda maintenance topper, necessity of it being irrelevant. Again, better safe than sorry?
There’s plenty of well-respected coating aficionados who coat and let it ride…with excellent results so topping is definitely not necessary in all cases. May as well throw ‘personal preference’ on the list as well.
I know that sometimes after washing, i just wanna spray something on the car and as long as it is synergistic (and easy) it`s just plain entertaining and maybe also alters the appearance somewhat. Wife is convinced that after washing, using Overcoat followed by PA Cosmic or High Gloss 12hrs later makes it pop more than using 1 or the other; dunno if i see it but since it entertains her and doesn`t hurt or diminish the performance of the coating by itself, may as well have some fun, no?
Maybe toppers/booster are kinda like using a foam cannon on a well kept car:
1. Even if it doesn`t help much, it can`t hurt
2. It`s easy
3. It`s fun
