Easy Way to Smooth PLA | No Sanding

I've Been 3D Printing for About Four Years Now and I Still Struggle to Find an Easy Way to Smooth PLA Filament. I Recently Made a Mistake with Polyurethane on My 3D Model, Which Led Me to Discover That It's Thick Enough and Dries Fast Enough to Fill in Layers. I've Put a Lot of Work into This Video, So Be Sure to Watch It Too! To Get Started, You'll Need the Following Materials: A 3D Printed Model with Visible Layer Lines. Any Can of Spray Paint That Bonds Well to Plastic. Fast-Drying Polyurethane - Clear Satin. First, Clean the Model of Any Dust and Make Sure It's Spotless. Next, Spray the Model with Your Selected Color of Spray Paint. Then, Quickly Spray a Layer of Polyurethane on Top. To Prevent Drips and Speed Up the Drying Process, Place the Model Under a Fan. The Paint and Polyurethane Will Mix and Fill in Layers, Holes, and Printed Flaws. The Thinner Each Layer and the Longer You Let It Dry, the Better It Will Look. I Waited 20 Minutes Between Layers and Then Spent an Entire Day Before Applying the Final Coat of Spray Paint to Cover Any Discoloration. Note: I Printed the Skull at a Layer Height of 0.3, Which Means Detail Was Lost During Printing. A Height of 0.1 Would Have Been Better and Taken Less Time to Smooth, But I Needed an Extreme Layer Height to Show How Much This Method Can Do! Remember to Read and Follow All Safety Warnings on Spray Cans and 3D Printers. I Hope Someone Finds This Helpful!
