Step 6: Painting
Once the entire frame is well covered, check for any obvious bumps or flaws in the wood. You may need to sand, fill and re-prime these areas. You may also choose to sand down the entire frame again. This time use 300+ grit sand paper and wet sand. Make sure the sandpaper is waterproof. Wet sand basically means you're sanding in the presence of water. You don’t need that much, periodically pouring some water from a bottle should be good enough. Sanding the primer makes a nice smooth layer for the paint to go on.
Finally, add the colored coat. Apply the colored coat in the same way you applied the primer except wait at least 24 hours between coats this time. If you’re satisfied by the way it looks right now, then fine, otherwise read on: once the whole thing is painted and dry, wet sand the whole thing with 400 followed by 600 grit sandpaper. Don’t worry if you sanded off all the paint in some areas. Follow up with a second coat now in the same way you did the first. This coat should look a lot nicer than the first. Now if you want it to look even nicer, you can wet sand down this coat too, this time with just 600+ grit sand paper. Be very careful because it’s really easy to sand off too much in some areas while trying to sand down enough in another area.
