For anything that has to be strong or shaped or scribed over, I use CA adhesive, worked while as "green" as possible after drying. Ditto to all the above. The applicator is pretty much the most useful for hard to reach spaces, such as the seam on a wing or the inside of a nacelle toward the wing that you just can't get to otherwise. But, you have to clean out the applicator with water, thus wasting more of the putty than you are using. Use a drywall scraper to fold the water into the plaster. Cut, scrape, and spread the basecoat plaster and water to mix them together. As you do that, you should notice a putty starting to form. Keep mixing until you have a smooth, spreadable consistency.

Pour the dissolved Borax into the glue mixture and stir it together. When you start stirring all of the ingredients together, you’ll see them reacting almost immediately. At first, it will look like the glue is clumping together, but keep stirring until you get a ball of putty with a relatively even consistency. I use the tip of a scalpel, just as with green and white stuff to apply it. If you get any drying out at the top of the tube and the material becomes too dry to work in, just add a couple of drops of water and give it a few minutes to rehydrate. Pour a small amount of water into the center of the well. Since plaster absorbs moisture from the environment, the exact amount of water you’ll need for this will vary. Start by adding about 1–2 US tbsp (15–30 mL) of room-temperature water to the center of the well. If the mixture seems too dry when you mix it together, you can add more water.

The putty should tear or snap if you pull it sharply, so it’s easy to use just a small amount for your project!

Vallejo for me too. Long, thin applicator that doesn't dry out (so far - 11 months) and a putty that you can blend in with a damp finger meaning MUCH reduced sanding afterwards which is great because I'm so lazy! Deluxe Materials Perfect Plastic Putty is a one-part, fast-drying, superfine filler with water clean up.I have gotten where I only use this putty for small, non load-bearing seams that don't require any re-scribing, such as canopy to fuse, where you don't want to sand at all or little. The pointy tip applicator has to be cleaned after use each time, and it is recommended to place the whole thing down into a glass of water to prevent the tip from drying when working.

If you want small amounts of of this type of filler, I would suggest getting the Vallejo putty. The tube version comes with a long thin applicator that has a cover. Pour 4 oz (120 ml; 4 fl oz) of non-washable school glue into a bowl. Silly putty is stretchy, bouncy, and fun, and it’s super easy to make! To start, measure out about 1/2 cup (120 ml; 4 fl oz) of school glue into a medium-sized plastic bowl. For the best results, use non-washable glue. However, you can use white, clear, or even glittery glue if you like! [1] X Research source Add 1/2 cup (120 ml; 4 fl oz) of water and stir until the mixture is completely smooth. You’ll need an equal mixture of glue and water to get the perfect silly putty, so measure out 4 oz (120 ml) of water and pour it into the bowl. Then, use a spoon, fork, or whisk to stir the glue and water together until they’re completely blended.Dissolve 1/2 tsp (4 g; 0.14 oz) of Borax in 1/4 cup (60 ml; 2 fl oz) of hot water. Scoop out about 1/2 tsp (4 g; 0.14 oz) of Borax powder and add it to 1/4 cup (60 ml; 0.14 fl oz) of hot water in a small cup or bowl. Then, stir the mixture vigorously with a spoon until the Borax granules have dissolved. Store the putty in an airtight container. When you’re finished playing with your silly putty, put it in a resealable plastic bag or a plastic container. If you’d like, you can also wrap the putty in clear plastic wrap before you put it in the container. This will help seal out any air, so your putty will last longer.
