A stopper and a filler serve different purposes in various contexts. A stopper is typically used to seal or close an opening, preventing the escape of contents or contaminants, such as in bottles or containers. In contrast, a filler is a substance used to occupy space, enhance volume, or add bulk to a product, often found in applications like construction materials or cosmetics. Essentially, stoppers focus on containment, while fillers address volume and texture.

There is a real difference. A flame-retardant bedding has filler that is not flame resistant, but the outer later is flame resistant. As for inflammable bedding, both the filler and the outer layer are both flame resistant.
304 and 304L are stainless steel electrodes. but in 304L, L denotes Lower percentage of Carbon content.It improves the corrosion resistance character of filler wire.
If there is debris on the stopper it might be preventing a good seal. Try removing the rubber stopper and wipe it off to remove any debris that might be on it. Clean out the hole that the stopper goes into as well. This will help ensure a clean seal between the hole and the stopper. Put the stopper back into the hole, making sure it is a tight fit. If it still leaks you may need to buy a new stopper.
Sand the fiberglass with a 400 - 1000 grit sandpaper so you can not feel a difference between the fibergass filler and the body of the car. Now you can prime it.
With a few exceptions (notably melting ice) objects expand when heated. If you run hot water on a bottle neck, the heat is applied directly to the bottle and only indirectly to the stopper inside the bottle, so the bottle heats first, and thereby expands sooner than the stopper does. An expanded bottle will exert less pressure on the stopper.

Maintenance free batteries have no filler caps and you do not need to check the level nor add distilled water.
The reagent bottle is not used for dropping, having only a common stopper.
The volume of the stopper can be calculated by subtracting the initial volume of the water from the final volume. In this case, the volume of the rubber stopper would be 30.9 ml - 25 ml = 5.9 ml. Now, divide the mass of the rubber stopper (8.46 g) by its volume (5.9 ml) to find its density. Density = Mass/Volume, so the density of the rubber stopper would be 8.46g / 5.9ml = 1.43 g/ml.

To remove a glass stopper, start by gently tapping the sides with a rubber mallet to loosen it. Then, carefully twist the stopper while pulling it upwards to remove it from the bottle. If the stopper is still stuck, try using hot water to expand the glass before attempting to remove it again.
