Nice work! What paint did you use to paint the boiler?
I buy the paint from Walmart, here are the photo's of both the Blue & the green that I use for most bases, the blue is my favorite,


and the green


I had a little trepidation about using this paint for the #45 as the heating base gets so hot , so far the color has not changed with a 300W initial heat up , the paint gets a bit tacky but is not discoloring , hopefully with a few more heat/cooling cycles it will cure in hard.
