As for Layering, here is a quote from Mike Phillips, Technical Writer for Meguiars:
2-3 applications of anyone's product to an automotive finish and you will have reached the maximum potential that product has the ability to create on a particular finish as it exists at that time.
So if by layering you mean 2-3 applications, then yes it’s layerable. If you mean, can you keep applying the product and with each application, begin to build a measurable film-build, or the finish will get better and better and better with each application, then no, it’s not layerable.
Now follow me on this one…
Once you have reached the maximum potential of a specific car’s finish, another application of the same product will not take the results to a higher level. It will maintain the level you have previously created, but the idea that a clear coat can be come clearer, and clearer, is... well... ridiculous.
For example, say you have a piece of glass that is perfectly clear and perfectly clean. If we give this piece of glass a rating such as, 100% Optically Clear, how can an application of a film coating increase the rating to say, 101%?
Isn't 100% the maximum potential of the piece of glass? (I mean, if 100% doesn’t mean 100%, then what does it mean?)
Paint is actually dramatically more susceptible to change in its rating because paint is more easily dulled. So while some products can take a car's finish to its maximum potential, (as we all know), some products can easily dull a finish and thus move the appearance quality, or rating of a car's finish downward, away from its maximum potential. Contrast to glass which is usually only dulled through abrasion.
Point being, if your using a product that looks good in your eyes, and if you apply 2-3 coats in any given polishing session. After you wipe of the 2nd, or 3rd application, a 4th is not going to add or increase any visual aspect of the results your previously achieved with the 2nd or 3rd application.
Now... as time goes by and the results are diminished, say through washing or inclement weather, then, yes, re-application of your favorite product should quickly and easily restore the finish to the level the previous applications achieved. That is unless the finish has been neglected for a long period of time or underwent some type of finish-abuse.
I'm in the camp of applying your favorite product often to maintain the maximum potential. I don't believe that applying multiple applications of a product will hurt anything, but I also don't believe the finish will get,
* Darker and darker with each application
* Shinier and shinier with each application
* Glossier and glossier with each application etc.
Once you’ve reached the maximum potential... it's time to step back and admire it, not apply another coat.
It's like the term, �hitting a wall�, something a really good detailer can do on every car they detail, thus the reason they are a really good detailer, they always hit the wall.
Does any of that make sense?
Have to go....
