How fine -grits- do you sand tops and b/s before applying epoxy. How fine between coats of finish? Do I need to use microbeads with System 3 for filling Macassar-if so what proportions? Thanks |

Straight grained mahogany or EIR, and tops, P220 works fine, although P320 is a bit 'safer', perhaps. P400 is as far as I feel is necessary for a laquer finish guitar. If I'm oiling something, I go all the way to 1500 and steel wool. |

220 is fine for epoxy and Laquer. Oil finish is different, you have to go much higher. Tracy |

Hi Bob! Sand to P320, safest way to remove all scratches. I don?t recommend the use of microbeads with epoxy for porefilling, because this are small glassbubbles. I use instead an Thickener called Aerosil. Its easier to squegee it into the pores, the result is much better. |

Bob, you asked about sanding tops before epoxy filling. I sand tops to P400. You do not need to fill tops such as spruce or cedar. just a seal coat of shellac is all that is needed on spruce and cedar tops. I don't use microbeads except on very porous woods. |
