Stove Pipe Paint

Which brand/type is best. Ok, go!

Depends on the pipe mfg and age of the pipe. Normally I would recommend Stove Brite, but I found out the hard way that doesn't work on all pipe. We have some 2006 Simpson DuraVent DVL that I touched up with Stove Brite and the acetone in the paint acted like a solvent and caused all the paint it touched underneath to alligator badly. I had to let it dry and sand it all off. Turns out they used a lacquer based high temp. I've been told that M&G now uses Stove Brite. My recommendation is to call the pipe mfg first or at least do a small test spot that this out of sight.

Pipe is 1 year old, and was shot with what I believe to be Stove Brite by the installer. I have no idea what the brand of pipe is. It's single wall, and goes up about 3.5 feet and has a 90 bend, at which point the paint is flaking off. The paint closer to the stove has become chalky. Bottom line is that it needs to be repainted. I will be removing pipe to clean out top of stove where the damper is anyway, so I figured I'd paint the pipe again after scuffing it up. I can get Rustoleum high temp paint locally for much less than the Stove Brite I see online for $15+ (and $15 shipping). Thought I might give it a try. I'm wondering if this will be a yearly thing, and if so, I'd much rather just use the less expensive stuff.

What temps is that pipe seeing? Is there a thermometer on it?

350-600 depending on the time in the burn cycle. This is measured about 18" above the outlet of the stove. There have been a few times when it has been higher, not on purpose.

Sounds ok. Usually greying of the paint is a sign of overheating the pipe. I have had pipe up to 900F briefly without issue on the old Jotul. Sand and spray with high temp 1200F paint.

I took it all apart, scuffed it with scotch brute, cleaned it. I then painted it with 2 coats of Rustoleum high temp (1200*) paint. We'll see how it holds up. I'll try to report back here after a few weeks of burning this fall. Cost was appx $6/can. I bought 2 cans and used about 3/4 of one can.

Rustoleum also makes a High Temp Ultra header paint in flat black, good to 2000°F. I find I prefer the finish it leaves over their 1200°F paint, and goes on a little easier in my opinion. Worth a try if this one doesn't hold up.

Here are some pics of my stove painting.
VHT Flame Proof Flat Black very high temp 2,000 Deg F car header spray paint in the fire box and Stove Bright Satin Black 1,400 Deg F spray paint on the outside.

When I do stove pipe, I do the VHT Flame Proof flat black as a primer and then the Stove Bright Satin Black for the finish coat. Comes out super nice!
