Rather than keep cluttering up other theads, thought I would post a couple of photos of the paint I have found works best on fireboxes exposed to flame heat:





This stuff is made in the USA by a company that is actually called VHT.

Here is their website:  www.vhtpaint.com

They make several varieties in several colors...but I have found that the "Caliper Paint" in satin black works best for me.  It is heat resistant to 900 deg. F (482 deg. C) and it requires a relatively low oven curing temp:  200 deg F (93 deg C) for just one hour.  I always repeat the heating cycle a 2nd time to ensure it is thorougly cured and hardened.  The lower curing temp is important if you happen to be curing an item with soldered components which can melt at higher temps.

After the satin black has cured it is easily buffed with a rag to get a higher degree of gloss, so you can leave it satin or gloss it up using the same stuff.

Thank you for this post...will go for caliper-paint on my next project

Haven`t crossed my mind before, eventhough i several times has painted calipers and other "hot" parts years ago when i worked for Volvo
Perhaps because we (to keep the confusion max`ed out at all times) back then used stove-paint which has a less glossy appearence...

Aha. My main beef with high temp paints had always been that their "black" was instead a nasty charcoal-grey excuse for black. I had found however that Thermacure's "VHT Stove Paint" was advetised as satin black and actually was proper smart black hence why I swear by it.

Now, as for this VHT stuff, any pics of the finish please

Duplicolor makes a good high temp paint with a good
selection of colors. I also found that Rustoleum makes
a 2000 degree primer that makes a good base coat
for most high temp paints I have used.
