PC when humidity is high...

all your doing is creating static with the shaking so one is attracted to the other.
you might be able to drive some of the moisture off the bullets with some heat, but the powder sucks moisture up too.
[that's what ruins the powder BTW]
when they are both 'wet' the pos/neg charge is nullified so things get tough.

I'm sure I could find an answer on the other site if I dug. But. When humidity is high, what do you guys do to get the pc to stick when dry tumbling?
Sounds crazy but seems to work for me so well that I have slight problem shaking off the excess powder. I tried pcing some 480's for son several weeks ago but powder would not stick well enough for anything but a very thin mottled coat. It was foggy and a slight rain. based on a test several weeks before, I added some Ideal yellow 77 wire lube to the bullets and coated thoroughly. I then washed with a garden hose. then a final hot water wash and dried. This time I got a very heavy powder stick and had to rap every bullet against the container to remove most of the excess. This procedure is added work but when you have to have bullets it gives me a way to get them.

On days when the humidity is high I just coat my bullets in the house and bake them on the back porch. In general I do most of my powder coating in the fall and winter months when the air is very dry and ideal for powder coating. I can coat enough bullets to last me through most of my shooting needs when conditions for coating are not ideal out in my shop.

I live in Michigan, a pretty humid place most of the year. I haven't seen that problem yet. Sometimes I shake a bit longer. Rel. Humidity of 30-75% pose no problems. I don't remember trying to PC in a fog or rainstorm.

I pc in hot fog and drizzle, in an un-insulated steel building with the walls sweating water. Seems that's the conditions every time I have time and need to do it. Use good polyester powder and shake them hard enough, long enough and the powder will stick.

I'm gonna try Bama's wash trick, it seems like a certain amount of mechanical abrasion has to take place before the powder will adhere, maybe a wash will help reduce the shaking.

I’ve seen where several guys preheat the bullets a little before PC’ing in humid conditions.

Like I said I have never tried it but have read several post about it and a couple videos.

Clumpy mess in my experience. There's a really fine line between just tacky enough and gooey.

Keep your PC in the house with the AC on, and tumble the bullets indoors in a sealed container and place them on the baking sheets back in the garage. I suppose you could also do the same in the garage with a dehumidifier. I forgot at first that you live in the Pacific NW, and that you have some really beastly humidity to contend with. My sister used to live in WA state. She told me there are only two seasons up there. Cold and rainy, and rainy.

Just an FYI that part of the state is west of the cascades the east half of the state is desert, and farm land.
Oregon s the same way part of the state is desert farm land and part is coastal. That’s why we call it the wet side for those of us dry landers!!
I live in Yakima and we only get 8-9” of rain a year currently we have not had any ground wetting rain for atleast 3 months.

So it never freezes and never gets over 65? Why isn't the population like ten million?

The internetz are great, but there's no substitute for the opinion and information on a particular place from real people who live in or know the area. Summers are getting to be nine months long here and the humidity only lets up in the afternoons when the temperature gets near 100. Wifey is perpetually miserable unless indoors, and she was born here like me. I refuse to live where shoveling snow is a daily activity. Looking to the future for a part time summer home in a remote deserty area. We own a house in sw Colorado but recent legislation has made the whole state rather...not good anymore for long stays.

So Yakima gets over a hundred in the summer and can see below zero in the winter.
It’s not excessive.
Every once in a while we get a summer or a winter that really sucks.

We have four solid seasons so the heat does not last long and the same with the cold.
There is not a huge job base here it a lot of farming and small manufacturing.
And our full service boat marina we are the last one left:cool:
