Filling 3D prints to remove the filament lines is essential to creating finished props. In this tutorial I talk about the process generally, and then show my favorite method using Bondo Glazing and Spot Putty thinned with acetone to rapidly apply fastdrying coats. I then sand the filler smooth, and move to using a final pass of Filler Primer, that gets wetsanded smooth. A final coat of primer reveals the smooth surface, ready for paint.

Important: Acetone melts ABS, so this will not work with ABS prints without likely destroying the print below. The prints in this video are all PLA.
