"New" chimney still stinks after a month of 24x7 burning

I recently repainted a portion of my single wall chimney with 1200* stove paint. The first few fires, I expected that "curing paint" smell in the house, but it's been a month and I still get it when the stack hits 550-600. This is the maximum I run the pipe at, but I've hit it multiple times, and each time it goes over 500, I get the smell, and it's just as strong as the last time. Any ideas?

Yes, it is. I can do that... just when the wife is at work!

I have heard if it gets put on too thick that stuff will almost never cure. I think the hotter temp might just do it though.
