So when you guys finally get to the level sanding and start to work up the through the grits to get to the buffing arbo stage of a build, provided you’re doing lacquer, do you do it by hand? Do you use a small sander? I’m open to upgrading this part of my building process … Just curious as to what method you all like Sent from my iPhone using Tapatalk |

By hand with a 2” gum eraser as a sanding block. |

I could use my Festool 5” random orbital sander, but I prefer going slower and playing it safe. I use small sanding blocks of varying rigidity. Maybe someday I’ll feel OK going faster. |

there are big erasers at the dollar store for Big Mistakes also you can get the pipe insulation and make your own for the hand blocks as for wet sanding a small squirt of dawn in a water bottle makes a good wet solution |

I also use big erasers to block sand, and a 6" piece of clear round gas-line hose as backing for the roundy bits.... For waterborne lacquers like EM6000, it is not recommended to wet-sand with water. After dry sanding to P800, I wet sand with Wet & Dry with P1000, P1500, then P2000 using light mineral oil as wetting agent. Old English Lemon Oil is simply light mineral oil with a lemony fragrance - works great. After sanding to P2000, very little effort on the buffer is required to polish it out with no scratch marks. |

It was super, super tedious though so I switched to dry sanding but with 3M Gold Fre-cut sandpaper followed by Mirka Abralon pads (and switched to Endurovar). |

When I tried wet-sanding with W&D after dry-sanding with P800 3M Gold Fre-cut sandpaper, I experienced witness lines and even some film breakdown between layers (on a run of 5 guitars). Very frustrating. The finish had cured for 14 days after the last spray session. I scoured the Target forum and the consensus there was to avoid water, and use light mineral oil instead. No problems since, and the process is no longer tedious... |

When I sprayed EM6000 I wet sanded with low-odor mineral spirits and had no problems. |

For level sanding I will use an orbital sander for the "flat" areas but stay away from the edges. I will do the edges by hand. If wet sanding I will use a few drops of dish detergent in the water. I try not to remove any more finish than I have to, and will move through the first couple of grits before the surface is completely level (still see some shiny spots). |
