On props and pilot maintenance....
Do whatever it takes to not put chips in the prop in the first place, whilst there is bad luck it is still possible to operate over gravel large and small with a high horsepower engine and low prop clearance and not get significant dings.
Run ups can be brief and on the run into wind, this high power static run up stuff is a little last century.
Wash your prop.
Bug guts can contain acids aside from a range of chemicals likely still unknown to science, dirt contains salts none of which rammed into a porous sand blasted LE at near sonic speeds is going to help prevent internal corrosion. Detergents used for washing it need to be chosen wisely with regard to PH and corrosive qualities. At the risk of making a recommendation CT18 from Chemtec seems pretty good and the fact millions of truck owners swear by might be worth something.
After washing and when dry, really dry, wipe some 50w oil along the LE, it will help seal it and slow the progression of contaminants into the grain structure of the blade.
This tip is not legal, but past to me from an older wiser seaplane driver, use a hard smooth surface instrument, side of leatherman, shaft of a large screw driver etc to rub the rough porous sand (or water) blasted LE this will put a smooth worked finish to the LE. Seems to me this blending of the surface grain leaves the LE a little more tolerant to ingression of contaminants.
Little of the above is relevant to employed pilots as the general rule is turn key and go, maintenance cost are someone else's concern. But aircraft owners who pay there own bills might garner something.
