I am new to this forum, and would like some help. I am involved with the Waterloo Central Railway, and we have a Montreal locomotive Works 0-6-0 #9. She is a 1923 switcher which we run often during the year for excusions.
We are going to be retubing #9's boiler this winter, and we have reason to believe that Apexior is a good product for coating the inside of the pressure vessel.
I would like any information on the practical use of this product. Do you use it on your engine? Any draw backs? Any tricks or things we should know? Any reservations using this product?
I have read the company propaganda but would like some actual testimonials from guys (and gals) who use it.

Any help would be appreciated.

Greetings from Canada

It's 30 odd years since I was involved with painting the inside of a boiler with it (and the flues before fitting them) but it did seem to reduce corrosion as we got 11 yrs out of the flues. IIRC there were two types #1 and #3. One smelt more like cellulose paint and dried matt black - this was for the 'wet' side. The other seemed like it was bitumen based and was for the exterior of the boiler. Sorry can't be more help.

Call it propaganda if it makes you feel better, but the fact is that it
works and has been a staple in the boiler industry (including steam locomotive
boilers) for at least 75 years.

Well worth the effort. Be sure and have lots of air circulating inside when you're doing it.

The metal has to be clean. By "clean", that usually means sandblasted clean. This is difficult for firebox areas.

I will let others chime in about surface preparation, but know that "clean" is the word of the day.

Consider your water treatment as well - if your treatment works by creating a thin layer of inert material on the steel surface, this might interfere.
