I didnt start on any of my nice mods. i started off on my natural and have some ideas of how you can brush it in steps. You will need the following: 1. mod you want to try out on, not suggested on first go on high end. 2. Sandpaper, will need 1500-2000 grit, 800-1200 grit, 320 grit, and maybe 160 grit if you want a deep brushing. make sure the high grits are wet/dry capable. 3. an empty spray bottle filled with some water. 4. a few towels or rags you dont mind getting grimy. 5. location close to sink to rinse occasionally. 6. a pair of gloves latex or what not. 7. a mask to make sure you do not inhale any particles you may be shaving off.
Steps.
1. Always clean off mod first. no battery so there is no chance of firing. just need one tube at a time. if you are looking to cover up markings make sure you do so beforehand with either tape or vinyl.
2. Always start with highest grit sandpaper first to see the look before going lower. Never want to start off with most aggressive, because there is no going back.
3. spray water from bottle onto tube so it is covered liberally, then in one motion i prefer up and down, start to use sandpaper on the tube. do not use pressure as it is not needed. i always keep the tube wet on the area i am sanding even if that means reapplying water from bottle
4. once done with first sand, wash off tube and spray sandpaper with water from bottle to get the particles out of the pores. it should turn from dark to light.
5. repeat step 3. i typically go 3 times per grit.
6. If the brushing is not as deep as you would like then step down one grade of sandpaper. So if you start off with 2000 grit then go down to 1200 grit. Repeat steps 3-5 with the new sandpaper and decide if you like the finish.
7. Once you decide upon the final look of your brushing work your way back up the sandpaper levels to get the smoothest feel you like. ie. go back through steps 3-6 till you reach the highest grade.
then finally dry everything off and clean up the mess you have made and enjoy the look of a new brushed
device.
I suggest using a piece of metal or a older mod you dont mind trying on first.
i will attach a pic of the deep brushing i did.
