I noticed some flakes in my powder when measuring in the scale. It seemed to be the coating inside the RCBS powder measure coming off due to rust. It's stored in a climate controlled basement also. Would you be comfortable using it still? Any help on what to do? Ditch it and get another or see if RCBS will replace it? Here is a pic  |
| I'm interested because the inside of mine is porous like swiss cheese so I can see this happening. Some other parts of mine got rust that I wiped away with CLP, and worried that the same part of mine would be impossible to clean, and rust if I did clean it. I've thought about just smoothing mine with a buffing wheel or something, but we'll see what others say. |

This is not as uncommon as it used to be.....unfortunately. I bought another last year and mine was clean, but this is the third "rusted" complaint,on three forums, I've read in the last 4 months. Don't know if RCBS is buying out-of-country castings on Uniflows now or not, but the following is a quote from another forum where the customer called RCBS: (my underlined bold)
Just talked to RCBS. They said sometimes in the casting process, the sand will adhere to the inside of the chute and there will be improper cleaning after that process. He said he has seen a couple come in like that. Normal consumer cleaning will not clear the melted sand away. Anyway, they are sending a new unit with hopper attached plus a new measuring screw. DO call RCBS soon. Folks, if you buy one locally check inside before you buy.....if by an internet source....check when you do the initial degreasing required on any new casting. If the problem is there call RCBS. I think they will get to the bottom of this soon, but there's some probably still out there on wholesale/retail shelves. I remember when Hornady had a problem with their LnL bushings a few years back.....embarrassing....but they acted quickly and took care of the problem. Things happen to all companies....the good ones fix 'em fast and take care of the customers! Hornady did.....no doubt that RCBS will too. BTW, Dryflash3's paste wax treatment is just as great an idea on a clean one too. It improves throws....makes them even more repeatable. |

From what I read, rust is easy to clean compared to the melted sand that looks just like rust. That's why I underlined. I'll see if I can find a picture on one of those threads. Will post it here.
Found one....this is what he could get out with a lot of work.....unfortunately only the tip of the iceberg. RCBS replaced it. |
| About 4-5 years ago, I had a new Rock Chucker kit with a Uniflow that had flakes of paint falling out with rust. The Rock Chucker had machine marks on the ram that looked like it was machined with a wood rasp. The whole thing looked like a Harbor Freight product. I hope they improved, as I like RCBS stuff. I now have a 60's vintage Uniflow that works flawlessly, and replaced the RC with a Redding T7. |

That is weird. I live in a humid climate, and my Uniflow measure has sat in the garage for years. It is conditioned space and keeps humidity reasonably under control, but I don't THINK its any better than where you guys are keeping your stuff.
I have never had any issues with rust, although my stuff is pretty old. Dryflash has the right treatment, but in my view you should not have that rust problem. I WOULD call RCBS and see what they have to say about it. |
| Mine was new, out of the box. It did not have some little bit of surface rust from high humidity- it looked like the casting sat in salt water for about a year then was painted over. My guess is they use a casting sand that is acidic and the parts were not cleaned before painting. Large flakes of paint falling off due to a layer of rust underneath. |

I got one about 6 months ago...the big RCBS unit with the quick change adapters...it started rusting within a few days after I degreased it. I have tried everything but paint. I may try the paste wax. But to be honest with you the thing is very inconsistent and after the expense of it I feel let down. I was so hoping it would work as good as the box said it would...guess not

Quoted: What I would do is wire brush off the rust and coat the inside of the measure with paste wax. I coat the inside of all my PM's with paste wax. No it doesn't affect the powder. Here I'm coating the inside of a PM with paste wax. |

I have only used the Minwax, but other posters have said they used car wax. Which one, can't remember. Carnauba wax is the ingredient you want to look for, that's what's in the Minwax. BTW, nice to see you drop by. Been awhile.  |

Quoted: Sorry I didn't get back to yall. I called RCBS and they said to send it back to them with a note of what the issue is and they'd take a look at it and see what they could do. Should I go through the hassle or just do what dryflash recommends? I would send it back, I'm sure they will send you a new rust free PM back. They have great CS. |

I am wondering if the wax treatment would work as a good rust prevention product for die exteriors.
I have been looking for a solution other than oil. I have a good silicone spray I was going to try, but this might be better. Thoughts? (Not trying to hijack the thread, but it was already brought up) |
|
Quoted: Timely. I was changing powders last night and noticed some Varget stuck to the inside of the measure just above the plastic drop tube. I'm sure it was well degreased. What's the best way to apply wax in that area? |
