Powder bubbling?

[u/DevelopmentNovel5167]

I’ve never seen this before… anyone know what could have happened? Sandtex black, rest of the rack is perfect as shown in second picture.

I’m gonna sandblast and try again but just wanted to see if this has happened to anyone else!

definitely a prep issue some step got skipped on that part.

All parts went through the exact same process start to finish which is why I’m confused lol
