Hello all, I hope you're doing well! I am covered in splatters of wood filler, which are all somehow smoother than what goes onto my 3d prints. I've tried various different amounts of wood filler to acetone (wavering around a general 2:1, though the latter's been a bit higher or lower (I have been eyeballing it, as I have no turkey baster with which to extract the acetone from its unwieldy metal cradle)), and all of them have come out weirdly... grainy? chunky (as seen above)? Absolutely not like what I've seen in videos where people use wood filler. Clearly something's up, but I don't know what. My theories:

\- Incorrect ratio of ingredients  
\- Dry wood filler getting mixed in accidentally and messing with things somehow  
\- My brushes suck  
\- My fingers (used when I got tired of the brushes sucking) also suck  
\- I got the wrong kind/format of wood filler?  
\- I got the wrong kind of... acetone...?  
\- My mixing bowl is bad?  
\- My mixing is bad? (Do I need a mortar and pestle?)

The wood fillers I've tried have been DAP All Purpose Wood Filler and Gorilla Wood Filler. I've also tried water and that was worse. My prints are all in PLA and have both had and not had some light sanding. Anyone have any ideas on how to fix this? 

Acetone and Wood Filler Calamity, or Skill Issue?
