This is going to be a bit deep but been thinking about this a lot over the last lot of weeks, to me there's far more sealants coming onto the market the last lot of months than waxes almost as if company's are focused in on this, so is wax as we know it dead and soon to be a thing of the past or is it the fact you can buy in sealants and bottle them as your own meaning it's financially better to sell them.
I love a wax but with all the sealants round now is the market big enough for both?
Continuing advances in coating technology means there will always be new stuff coming onto the market, products offering increased durability, longevity and improved hydrophobic qualities.. and so on. These are a very attractive proposition to those who are time limited looking for easy to use, once/twice a year applications. Maximum impact for minimal effort.
In terms of wax, I think there will be continued focus on further developing hybrid waxes, but imo, there will always be a market for traditional wax, especially 'bespoke' premium waxes. It may be the mid range waxes that take the hit.
Ultimately, more consumer choice.
I don't think wax is dead at all.
