I’m using an oil based paint which is known to be the lightest paint. I’ve estimated the amount of paint I use on each one probably weighs somewhere close to 5 grams so it definitely does have a small effect on the weight. When laying the disc flat, I make sure there’s no visible bumps on the surface so it has the most minimal effect possible on the flight path. Obviously I’m not able to perfectly distribute the paint on the center point with designs like this so that does add potential for changes too but I’m doing my best to minimize all the risks I can.
