Hello all, I was wondering if you know the equivilant sand paper grades to the different color scotch brite pads? green = ?, marron = ?, white = ? stuff like that. I was wanting to use them with wax to get a smooth and 'want to touch' finish on EM6000. Thanks for any info |

All three , green , maroon and grey are abrasive and will leave scratches on your finish if you are not carefull . The grey is silicon carbide based as well. The white on thhe other hand should be non abrasive and generally can be used to buff by hand. I would recommend using a scrap and testing prior to using ANY abrasive pads. I have had many cabinet customers in the past purchase the white for buffing between coats because its non abrasive. |

I use the Maroon pads on bare wood inside the guitar. It's about equivalent to like 320 grit or so. Not recommended for finish work. Works great for cleaning up the interior of the box though. |

The maroon pads are great for scuffing between the first oil varnish coats, the grey pads for the corners. After a good build (4 coats) I switch to 320 grit and blocks. The maroon, grey and white can be used for polishing frets as well, right before buffing. The white is roughly equivalent to #0000 steel wool, the grey #000, maroon #00 and green #0. As John points out, the maroon or grey will give rosewoods and hardwoods a nice shine inside the box, but I prefer the 3M super-fine foam pads for that. |

Thanks for the info guys. I have been applying wax over oil based finishes with 0000 steel wool to get a really smooth feeling finish. As I understood it, you did not want to do this with the waterbased EM6000 due to if any stray fibers left in on the finish would rust or discolor. I was wondering if I could us the the white pad instead of the steel to apply the wax. What do you think? |
