It has got very strong sealant properties but overall it's just an awesome wax. So easy to use, looks pretty near enough BOS and will bead and sheet water.
In saying that if he just loves to wax all the time and he wants it to feel special just buy Carbon. Money no object non durable wax? Swisswax Best Of Show. The oils will wash away on a daily but show cars or garage queens, BOS is lovely.
He'll love Swisswax ease of use if he's used a pot of Glasur. It's old school beauty.
If I had proper mobey i'd have a pot of Vintage.
Oh and you have others like Lusso Oro that imo is one of the most underrated waxes ever made.
Ant no way could I spend money on Illusion knowing for a few quid more I could own a boutique wax. I just can't look past the packaging.
