Deluxe Materials Perfect Plastic Putty is an excellent one-part acrylic filler that goes down smooth and is easy to work with. Even when dry, it can be removed with a damp cotton swab or paper towel.

I’ve sometimes found no sanding is necessary to get a smooth line, such as when filling a wing fillet.

If it dries up inside the tube, don’t toss it away. Use an eyedropper to add a couple drops of tap water, shake well, and let sit for a few minutes. The water softens the putty so it’s like new again.
