I ordered my MkIV chassis uncoated because I wanted to make a couple mods and clean up the frame prior to PC, and I also wanted a color other than black. I ended up spending way more time cleaning up weld spatter than I expected. You don't realize how much weld spatter is on the frame until you see it on a bare frame and have to clean it off. All in all, I'm happy I ordered it uncoated but it was a lot of work to clean it properly and definitely more expensive to have it coated locally. All that considered, I'd still order my next one uncoated again.
