So i acquired a blast cabinet for free with a 20 gallons of some glass beads, and i have a ton of questions (not really  )
first off, i have 80 grit glass bead, would that work to remove blueing from a firearm second would the finished bare metal hold up duracoat (aerosol) paint third, would i need to degrease the parts after im done blasting them and finally if a mistake is made during the duracoat process, can i reblast and start over Thanks in advance, of course by now you may of realized im new to refinishing any firearm, i usually just pay to have it done --------------------------SET UP------------------------------ i have a 13 gallon compressor, i set up with a water trap filter a small shop vac, and waiting on a dusty deputy to arrive in the mail and a decent sized cabinet to do firearms |

Be prepared if your compressor dies. Blasting is very air hungry.
Prepping for paint, aluminum oxide works better, 100-120 grit. If your media and air is clean, you do not need to degrease after blasting. And yes, if you make a mistake, you can always blast everything off and start from scratch. |

Thanks, ill get a bag of some aluminum oxide then, on a side note, what would be the worst case scenario if the compressor dies, i assumed i would have to wait for it to refill no? |

That air compressor you have is going to make this whole project VERY slow going. I started with a 60 gallon, single stage 4 hp setup and it was REALLY bad. I now have a 80 gallon, 2 stage, 7.5 HP, American made Champion compressor and it is actually kind of therapeutic! Like you said, the worst that will happen is you'll have to wait, but with a 13 gallon compressor you'll be doing a ton of waiting. I would go ahead and pick up to aluminum oxide. I would also degrease again after blasting as that is less time consuming than having to start over if you find oil on the gun later. Remember, light coats and flash it in-between. Good luck! |

first off, i have 80 grit glass bead, would that work to remove blueing from a firearm. Definitely get the 100-120 grit aluminum oxide. 80 grit will work but you will need to take a scotch pad or 220 grit sand paper to knock down the rough finish. second would the finished bare metal hold up duracoat (aerosol) paint yup third, would i need to degrease the parts after im done blasting them. I do, you have to blow off or wipe off the blasting media dust anyways so why not get a rag with some acetone or lacquer and wipe it down. Your media could be contaminated or greasy fingers too. and finally if a mistake is made during the duracoat process, can i reblast and start over. If you make a mistake don't let it cure. immediately scrub off the duracoat with acetone or lacquer and re spray. no need to reblast. Thanks in advance, of course by now you may of realized im new to refinishing any firearm, i usually just pay to have it done --------------------------SET UP------------------------------ i have a 13 gallon compressor, i set up with a water trap filter IF the 13 gal compressor is all you got grab or buy the smallest tip (smallest hole size) you can for the sand blasting gun. a small shop vac, and waiting on a dusty deputy to arrive in the mail and a decent sized cabinet to do firearms |
