I'm not sure if Polymer Sealant contains mineral spirits or not, but it is "...a blend of polymers, resins, silicones, and imported waxes."

In other words, like almost all of Meguiar's waxes / sealants, #20 cleans, polishes, and protects the paint all at the same time.

The cleaning agents would almost surely be chemical cleaners, or possible contain "diminishing abrasives". In any event, it is very non-agressive.

When you ask if it "breaks down the paint", I'm not sure what you mean. If you are implying that it is somehow harmful to the paint, I don't think a company like Meguiar's would make a product that would "break down paint".

Mike Phillips, a training specialist with Meguiar's, has posted here before. He has commented on the ability to "layer" waxes or sealants on top of your paint, in other words, layering sealant film builds. He is not in favor of this as polishes / waxes / sealants are made to adhere to and improve your paint. If your are applying a product on top of another layer (like Zaino), he calls this "waxing your wax".

Here is a quote from one of Mike Phillip's posts:

"Because Gold Class is a "Polish Wax" (or Polish Synthetic", if you will), it adds polish and wax at the same time, which is a good thing if you want to maintain your paint and only want to do "One Thing", after washing, i.e. apply a protective coating of wax.

If you want to truly "Layer" a product then you need a "Pure" wax or synthetic protectant. But... there is a point to just how much you can actually "Layer" a product.

Taken to the extreme, if you can truly layer a product, such as Zaino, then after enough layers... you would no longer be applying Zaino to paint but would in fact be applying Zaino on top of a "Film-build" of Zaino. Since Zaino isn't "clear", it is a tan colored lotion, layer upon layer would not make a surface "More Clear", but in fact would make the surface "More Opaque".

Make sense?

I have "layered" multiple coats of a variety of wax products... on purpose... to the degree of being ridiculous and there is a point of diminishing returns. That is, no matter how many coats of a product I apply, subsequent applications, "must" re-liquefy previous applications "enough" that a true "film-build" never accumulates to the point of actually being a viewable layer, i.e. if it is truly "layering" then common sense would tell you that after enough coats you would "See" the "layers"."

Thus, since most of Meguiar's contain polishing oils, instead of layering the film build, you are simply breaking down the prior coat, and re-applying the same first layer of product.
