In recent years, many "sealants" have come to the market and have gained considerable popularity. I've used Klasse sealant products for years. I've always let the sealant cure for ~24 hours and then topped with a high quality white caranuaba wax which produces spectacular final results in terms of depth and shine. I've recently acquired some Xxponet sealant, reportedly the very product used in the over-priced dealer applied "Cilajet" applications. I've had some communication with the guy who developed Xxponet and he recommends against adding the wax top coats. What's the conventional wisdom about this?
