powder coating seat post

Debating having bike powder coated.
frame, forks, seat post

Is your seatpost a snug fit today?
If yes, then it is likely to be unbearably snug after PC.
Of course thereís nothing stopping you from guesstimating the fit and either sand down the post a little or hone/ream out the seat tube a bit to compensate.
Also, while PC is tough, it isnít that tough. If you actually plan to use the adjustability, it will scuff and scrape.
And there is the clamp too.

It's a bad idea. Powder coating is fairly thick and will probably be thick enough to prevent the post from even fitting in the frame. If you could get it to fit, you would need to make sure you know exactly how far to insert it, because it will be scratched from being inserted in the frame. I have built several frames for friend who loves to color match everything to the frame. He always asks me to powder coat the seat post and I always tell him "No".

Have your powdercoater put a plug in the top of the seat tube before coating.

Can they mask to the known insertion point? Can you "guesstimate" thickness and use a smaller post that will fit after coating?

That's about the only thing that's practical and assumes you won't change the saddle height in the future. Otherwise the coating will make the seatpost an excessively (or impossibly) tight fit and will be scratched and peeled off if you insist on forcing the post in.

...powdercoat on a seat post is just an exceptionally bad idea. It's right up there with "Here, hold my beer."

Aluminum? If you have some friends in the metal fabrication business, ask if they know of a local or nearby plater. They usually do anodizing and you can get it anodized in black, blue, yellow, green or red. Maybe some other colors.

Might be if the owner likes the way you BS with him, he'll toss it in with something else that is being done and not charge much if anything.

Might be easier just to buy one the color you want.

Does anyone make seatposts in any color but black and "silver"?

Well of course they do.

Not asked but a valid comparison are quill stems, specifically custom made ones. The, pretty much now unavailable, stem kits has quills (the part that inserts into the steerer) that were ground a tad less then their starting 22.2mm diameters to both slide fit in 1" steerers and to allow for the paint thickness. Now the difference was that the quill had the job of tightening inside the steerer (with the wedge) and a usual seat post will get clamped by the seat tube and it's clamp. There's enough scratched and marred posts with even "correct" fitting to think that the added PC (which is especially thick a coating compared to a nice wet paint coating) won't get scuffed and scratched. Now what would be interesting is to see if a post that was one "size" smaller and was PC'd enough (might take more then one application) could fit AND also be able to be tightened AND stay that way after real use. Still I would expect cosmetics to suffer. Andy

for seat posts; zinc nickel plate steel or electroplate aluminum. Apply a lithium grease for aluminum to aluminum, nickel grease for steel to steel, PTFE-based paste [teflon] for aluminum to steel.

If you've got a friend in the anodizing business, they might try "coloring" a bare aluminum post.

Have it Cerakoted. You could even do it yourself. It is a thin, durable finish.
