I have been powder coating a couple years. It works decently well but it is not the perfect solution as the fan boys proclaim. I find it a PIA to mess with. Far simpler to lube size and shoot. But then I never shoot indoors and that would have a bearing on necessity. I also do not see a lot of difference in the cleaning. Certainly not enough to on it's own taking that route. I use it mostly to use up a large quantity of soft lead without the trouble of procuring tin or other hardeners.

Powder coating is work, but since you don't have to let the lube dry (at least with ALOX) overnight, you can cast, PC, size all in the same day.

Rosewood

These are the main reasons I haven’t jumped into the PC game. I have a Star sizer and commonly go out to the shop, fire up the pot and preheat a couple molds. Cast a few hundred bullets and drop them on an old towel in a box. When I have what I deem enough I’ll let them cool while I refill the pot and flux the new alloy. By then the bullets are cool and I’ll run them through the Star, it’s really fast being push through and I can do 500 or so an hour.
Then I’m done and ready to go, I’ll often go ahead and load a few hundred up for an evening shoot or the next day’s trip to the ranch.
With good fit and proper lube, alloy, and loads I don’t see enough leading in 500 rounds of 38 special to warrant a brush being passed down the barrel.

For me and my setup that I’m already familiar with and have paid for ages ago I see no benefit to swapping over to PC at this time.

This is method dependent.
There are a number of ways to get the powder on the bullets. Some are quite easy.

I've never heard of a bullet lube that required drying. Can you provide some details?

Liquid Alox.
The stuff has a bit of solvent to it and does require some dry time.
I've used it ... Never really liked it

I forgot about Liquid Alox. Tried it once thirty or more years ago before going back to regular lube. While it may work to some degree, it's messy and looks unprofessional. I've found conventional lube to be much better even if it requires a lube/sizer and dies.

I found it over promised and under delivered.
Probably does alright with a 38 wad cutter of typical loading, but try to get some heat to it. It wouldn't hold up.
