Are there any updates on the prop tape question? A number of us tried the 3M product sold by Spruce (https://www.aircraftspruce.com/pages/ap/prop_tape/3mproptape2.php) but found it yellowed terribly after a couple of years and looks unsightly. I did a thread search and came up empty-handed. A broader web search identified products by other names from other vendors, but when I check into it, it's the same 3M stuff as above. Any new info?
