A wax or sealant can only reflect what is underneath it, so a clean, level well-prepared surface is the most important consideration (85% of a surfaces reflectivity is its preparation) along with applied product clarity. If you apply a product over a surface that is dirty or one that has surface imperfections a wax or sealant will not disguise, but highlight them.
Polymers comprise of a long linked, flat chain molecule that lies on the top of the much smaller paint molecule. The chains cross-link to form an open link mesh like structure. The carrier system (solvent) flows across the much smaller dense paint molecules, leaving a very flat level surface.
Although they transmit the surface colour with very little distortion, the molecules are of a uniform size and therefore reflect the surface it covers with very little optical distortion, adding little if any depth, resulting in a very bright, flat silver glow.
Carnauba wax molecules are closed linked, which means that they only butt up together to protect the surface. These wax molecules form an egg-grate type (with the long axis vertical) mesh over the smaller paint molecules of the paint film surface, which gives it an optical, two-dimensional depth.
Colour, Depth and Clarity- the three factors concourse judges look for when scrutinizing paint film surfaces. Of the three, optical clarity is of primary importance, being able to see the paint film' s true colour by having a really clean surface, clarity will enable depth of shine etc to be seen, Carnauba wax dries to a deep, natural shine, in contrast, bees wax, paraffin and many synthetic waxes / sealants tend to occlude (cloud).
An Optically perfect shine comes from a clean, prepared and level surface; it improves the desired optical properties, surface reflectance. The other requirements are surface gloss, depth of shine and applied product transparency (clarity), which allows all of the components of an optically perfect shine to be visible.
The aesthetics of a vehicles appearance is very subjective to say the least, the only best wax or sealant that really matters is what looks 'best' to you. It really does all come down to; 85% preparation, 5% product, 7% application method and the balance is in the â€Ëœguyâ€â„¢ of the beholder.
