Hello!
Has anyone powder coated their brass overflow tank?
From what I understand, the brass tanks are 3 pieces soldiered together. The powder coat process requires heating the painted surface, so am concerned that the heat may melt the soldier.
Anyone have any direct experience with this?
:) Thanks!

Hi Bob,
I’ve had my header tank powder coated and when I took it in I do remember a discussion about soldered or brazed joints. If I remember rightly there was a trial process to check suitability and I think it was decided that the joints were brazed. In the end I went ahead with no problems. He did say if it had been soldered it would have just fallen apart in the coating process. I had this done about 2 years and 10,000 miles ago and no leaks. Hope that helps.

Hi David,
Thanks for your reply and direct experience! I guess it would make sense...brass being brazed....
I will also let this group know how mine turns out. I currently have it at the powder coaters.....

Hello colleagues,
Yes, I have "learned" the same.
My 230 overflow tank is mostly soldered and was "test-baked" at 200 °C before possible coating; it came apart. Thus, my tank could not be powder-coated ...
