I tried six coats of egg white on my bronze prop and cooling water inlet cover with amazing results!! Absolutely NO growth at all after 9 months! Just slipped the boat yesterday and was astounded at how there was no growth whatsoever! as was the marina manager and quite a few onlookers at the marina..yes! i have witnesses!....So,you have now all been informed on this very cheap alternative! This is no yoke!

... But,the truth is,it works!! or it did for me! and the procedure is simple...
Just clean prop to bare metal,I used wet/dry paper (120grit from memory),then paint on six coats of egg white,allow to dry between coats(I used a hair dryer,as it was quite cold 9 months ago)..that simple!!..and to best of my limited knowledge the egg i used wasn't laid by the hen (or a golden goose!) on a full moon with it's bum pointing to the prevailing trade winds

....
So,I do hope that others who read this,will give it a go and come back and confirm the wonderment of it all....best to leave the magic markers for marking magic! and the money saved from useing prop-sped would be better spent at the bar
