The most innovative company is....
CarPro.
They had one of the first coatings and one of the first products to prep for a coating (Eraser). They also have a unique method (suede towels / foam block) to apply it that many use for other coatings as well. Their Ceri Glass and glass polishing pads are pretty unique in the industry and the best out their.
Denim pads, velvet pads, etc... They also make likely the best trim coating out their - DLux. Reload may have been the first silica glass type sealant sprays. Their Fabric and Leather product is somewhat unique as well, as I believe its a "silica type" based product.
What about IronX? They came out with the first iron treatment in the industry using that type of color changing technology (I know Value Guard has been around, but that's multi-step and a different technology). Not to mention Iron X Snow Foam - waiting for the rest of the industry to rip off that one. Then comes Trix - iron and tar remover in one - who else makes that? Nobody.
They off so many unique products and are the first to offer them. I lot of the products have been copied by others.
Optimum gets major props for OptiCoat, but that's pretty much their only "unique" product. Opti Lens and the glass coating are sort of variations of that. I still don't understand why they don't make some type of panel wipe product to prep the surface.
Their are other innovators out their, but in reality they mostly just make coatings. I don't really see how someone could say a company like Meg's is leading the field in innovation TODAY. They make good products, but many of them are also available elsewhere.
