not easy to spread if it is a little cool. The brush was not in the package despite the photo (?) And we must provide a brush with stiff enough hair to smooth what has been spread with the spatula beforehand. So practicing in two steps is recommended. But we can only evaluate the installation, it will be necessary to wait for the next water outlet to know.
My boat was in port 4 months after it was launched. During this time, such growth had formed on the propeller that the boat had virtually no propulsion. I would not use again.
After less than 2 months having applied the prop-gel at my propellers (I've been using my engine almost 4 daysweek) the propellers were full of barnacles. Don't buy it!
I've put the prop gel on the propeller 4 May 2020 and after 2 months in the water it was all gone and the propeller was full loaded with stuff. Expensive product and not effective. test area The Northsea De Maeyer Wim
The product is so bad that it borders on fraud. The propeller was so overgrown with smallpox, that one had already noticed this before the crane date on decreasing thrust. I have plenty - whole tin - lubricated on the two-bladed Prop. Better keep your hands off it!
