I have a few spare sump drains valves that I can swap out in a few seconds. Your arm gets wet but you only loose a few oz of fuel when you get good at it. Also if your safety wire hole, in the wing is getting bigger than it should be, epoxy a fat washer on top of the wing skin to so that the safety wire does not cut into the skin any deeper
I'm like you, I look at them....Not every year, but every three or four...and it is easy, and quick to change them out if you are setup. I really like your idea of epoxying a washer on the wing. May I recommend Devcon AL. epoxy.....Maybe someday I'll tell you why I think that is the best stuff going...
I saw a small aluminum rivet installed (like sears and pop-rivets) with the core removed, used to beef up a worn hole. Thought that was pretty ingenious. Looked like a small grommet.

Would the above be an aluminum or stainless steel rivet, and would it be just a log book entry or should a 337 be submitted to the local FSDO? Do you think this might be acceptable owner maintenqance?
(Do you suppose this can be milked out to the six page record of the rear seat removal? It seems equally important to me.)
The aluminum rivet was probably obtained from Sears and installed with a common pop-rivet gun, therefore application for an STC with engineering data will have to be submitted in triplicate to OKC thru the local FSDO. A lie-etector test will be required in lieu of naming the FAA employees associated with these forums who will doubtless be furiously recording every sentence. (And the aluminum rivet must be of 1100 alloy.)
