Forget the gloves! What do you suppose the effect of this stuff would be if sprayed on the hull of my kayak? Do you think there is any chance that it might significantly reduce the drag of the hull as it goes through the water? A 5% reduction in drag would be an enormous boost in performance.

So, are there any hydrodynamicists here? Would this silly idea work?

One set of the hand sprayers would cover my hull (40 square feet) with about 20 square feet of coverage left over for abrasion touch-up. HOWEVER... after a bit of research I am pretty sure that that € 73 price is just for the bottles. Then, I'd have to spend an additional € 312 for the 1-liter (minimum quantity) bottom and top coat chemicals. That's $500 USD, more than I care to spend on an experiment. Then, the reviews I have seen on the hand spray bottles are less than encouraging. The bottom coat chemical is too viscous and streams rather than sprays. Note that these reviews are for different (but similarly expensive) bottles sold by Amazon, perhaps the genuine French-made bottles are better. Opinion seems to be, however, that you need a decent quality pressurized sprayer to make it work.

The product looks miraculous if it works as advertised, and I suspect that it does. But it does NOT seem to be meant for private, home use, and some of the distributing websites stress that point.
