A pro racer told me to "grease the threads AND the seatpost" on a new build and I laughed until I saw what corrosion did to his old frame
He showed me a cracked aluminum frame from a shop in Boulder where the seatpost had fused solid from neglect, and now I smear a thin layer of anti-seize on EVERY threaded part even on basic customer bikes, has anyone else seen a seized post ruin a frame?

Tried explaining this to my crew once and they looked at me like I was speaking ancient bike shaman language until I pulled out a seized seatpost horror show from the shop's scrap bin. Now I'm the guy who walks around with a little tub of anti-seize and greases things that probably don't even need it, like my coffee mug lid lol. Seriously though, I've seen an alloy post weld itself into a steel frame so bad the owner just scrapped the whole thing. Makes me wonder how many perfectly good frames are sitting in landfills because somebody skipped a 2 minute step.

Read somewhere that heating the frame around the post can break the bond.

Three months ago I swapped a friend's seatpost on a 90s Bridgestone and the whole bottom bracket shell came out with the post like a bad tooth. @loganl22 is right about the scrap bin, I've got a frame hanging in my garage with a carbon post frozen in an aluminum lug that I keep around as a warning to new riders. The worst part is the owner told me he always used "a little bit of WD-40" on it, which basically did nothing. Now I put a ring of grease on every seatpost like I'm seasoning a cast iron pan.
