This article is a conglomeration of two different installs because the Prussian Blue pics came out blurry on the Campbell Sailor shoot. Either way this is what it will begin to look like after lap fitting. The Prussian Blue will be evenly distributed when done. Be sure to use some forward pressure on the prop when spinning it on the Prussian Blue. This one still needs a little more but not much.
When sliding the prop off the Prussian Blue use a quick straight back pull, no spinning, and try not to drag it along the shaft as you can make a mess if your new "evidence". You will invariably have some drag marks but you want as much fit evidence left on the shaft as possible.
When all was said and done with the Flex-O-Fold & Campbell Sailor there was better than 90% contact between prop & shaft. The entire process takes about 15 minutes to fit a prop to the shaft.
