Title: paint on water side of fire box
Post by: coaldozer on February 01, 2014, 04:41:43 PM: :-\ I read in a post that the water side of the water jacket should not be painted . Figure this goes for fire box too . my firebox is a 120 gal propane tank with some nice thick paint . I started removing some but after 1/2 hr I had only cleaned up about half of the end. Does this really have to come off . I know the treatment needs to make contact with bare metal to work properly . I guess what I am really wanting to know is what kind of problems would develop from leaving the paint on ?

Not sure what those tanks are painted with, might even be epoxy.

I'll let wiser heads chime in here, I bet somebody already has experience with this one way or another.

I think he's referring to the outside of the firebox since it started out as a propane tank.

I have no idea how much difference it will make but if I were doing it I would just clean off all the loose paint and put a Y strainer on the line just in case it does start coming off eventually.
