Zymol has waxes that cost more than some cars. I am an avid user of Zymol's glazes, and as far as my own automobile is concerned (and yes, given proper prep work) I have yet to find a wax in its range that could match its intensity and depth of reflection, optical range, etc. But that's my opinion.
You will need to find out for yourself, however, whether a Zymol is as good or better than what you are using by doing a comparison between it and several waxes, using similar prep methods, and doing an in-person comparison, and using (only if the pics have a clear resolution) good digital photos to compare the response from the finishes of the different waxes.
Lastly, you will need to determine whether the price factor warrants the results from any wax. After all of this analysis fun, then you will be able to decide whether a Zymol is the right product for you.
