It's a myth that chiggers burrow into the skin. They don't, so 'smothering' them with a seal of nail polish is also fictitious. Whether nail polish relieves itching from a chigger bite is the question.
A cheap (dollar store) turkey baster can work as a siphon pump. Add a piece of plastic hose to get into smaller places.
Use aluminum foil (or cut up an aluminum can with scissors) to fashion a custom spout to direct the oil. Some mowers come with a plastic spout for this purpose that gets easily lost/never worked right anyway.

It's hardly impractical if you need a metal brake.
I disagree. The idea of an Instructable is to instruct on the processes and methods behind projects. Many people already have many of the tools listed. If you don't have a specific tool, there might be an Instructable on how to make one of those, as well.
Spray a clearcoat, so the brush doesn't smudge the image.
Try looking on Amazon or eBay for larger, bulk quantity purchases? Michael's is geared to smaller, craft-sized quantities (with their associated packaging and markup).I see a quantity of 100 6mm by 1.5mm neodymium magnets from China on Amazon for under $10. (I'm not linking to it, since I'm not advertising for anyone specifically.)
Adding some silicon dioxide (anti-caking agent) to your garlic powder might help prevent clumps (it's how the spice industry does it). Also, possibly adding something non-magnetic (such as a glass marble) might give you more 'clump-busting power' when shaking the grains loose.https://www.americanspice.com/silicon-dioxide/"Simply Organic" brand garlic powder is more coarsely ground than many "garlic powders" and is less prone to clumping. I buy it by brand specifically because of this fact (I don't care about 'organic' labels).
You could use a block of material with a hole to match the thread. Then drill a hole through the center for a screw with the point filed down to match the profile of the thread. The point of the screw will follow the thread. Accuracy is your friend.
If you were to attach a small piece of wood with a hinge to the top of the device so the other end rested on top of the paper towels, it would prevent them from unrolling in a breeze and you wouldn't have to fight with the bungee every time you wanted a towel.
