    Hello Everyone,

    It's almost time to paint my smoker build and i wanted the community opinion on what is the most reliable high temp paint that won't break my bank.


                   VHT: High heat paint mostly used on cars,  An amazing array of different colors

    Temperature: 1300°F-2000°F (704°C-1093°C)

    Applications: Headers, Exhaust Manifolds, Piston Domes, Inside Heads

                    Rustoleum:  Makes a product specifically for Grills,  very few color options,  i think this is the go to for most people.

    Rust-Oleum® Specialty High Heat Spray retains color and finish up to 1200º F. Apply to grills, wood-burning stoves, radiators, engines or other metal items. Provides rust protection.

                     POR 15:  Mainly used for cars.  Fewest of color options.  some people swear by this.

     POR-15® High Temp Paint is capable of withstanding extreme temperatures up to 1200°F and will resist cracking, chipping, and peeling. It is also extremely weather, salt and moisture resistant.

    P.S.  Some people use different temp paints on the Fire Box and Cooking Chamber due to heat differences. Why not paint the whole thing in what ever you put on your Fire Box?  Is there a reason?

    Thanks for your help on this

    VHT is what I used, however it needs to be sort of baked on to cure.
    • Paint must be completely dry before curing
    • Heat to 250°F (121°C) for 30 minutes
    • Cool for 30 minutes
    • Heat to 400°F (204°C) for 30 minutes
    • Cool for 30 minutes
    • Heat to 650°F (343°C ) for 30 minutes

    Oh wow i didn't know you had to cure it 3 different times.  I guess i read right over that.  Your smoker looks awesome.  I don't mind having to do it 3 separate times since i will dedicate a full day to it.  I read on the site that you have to apply multiple coats.  Is that where the 3 separate cures come from?  I see multiple types of VHT in your pics.

    "VHT provides a multi-high performance coating system for the ultimate in protection and quality. The system includes surface preparation, primer, paint and clear coat."

    Can anyone give feedback on the Rustoleum products and the POR 15 products?  It would be greatly appreciated.

    Not sure if you prime it then bring your temps up 3x for each COAT. So if you primed it with 2 coats, painted with 2 coats then used a clear coat it would be 9x you would have to bring up the heat?(3x for each coat). 

    I cant remember if I took a shortcut on mine, I may have primed then painted and did the heat thing...not sure, my brain is old!

    Yes its a bit of work and not sure if it's worth it. I did not use prep spray.

    The clear coat is to add a little sheen as the high temp paints are flat, or at least that's what I recall.

    I oil the firebox...

    what do you mean?  you only oil the inside right? or are you saying you oil the outside cause it gets so hot?
  10. sqwib

    Yes. inside and outside, sometimes I toss pork fat on he firebox to tease my neighbors.

    I also do some warming and cooking on the firebox.


    The inside top has a piece of steel as a baffle and the top don't get hot as it used to but will boil water no problem.

    so you didn't paint the firebox at all huh?  interesting.  What about the inside of the smoker?  Am i correct in understanding that after you clean it you don't paint int but instead wipe it down with cooking oil and run the smoker for about 30 min to an hour in order to season it and that's all that's needed?
  12. sqwib

    Yep I use bacon grease, any food safe oil (for lack of wording) you can consume will work, flax seed probably would be the best. You could even wipe it down with pork fat trimmings when warmed. Then season with wood of your choice, I actually seasoned with wood, applied the grease then seasoned with wood several more times

    On my GOSM gasser no oil is needed just a good hardwood smoke is enough but many guys will oil them too but its painted steel so I don't worry about it., I do spray the grates with PAM spray.

    The firebox is oiled every couple of uses depending on how well the oil is holding up, if I haven't used the pit in a while, the carbonized oil will flake off.

    If you put the oil on when the firebox is warm or its fairly warm out, the oil will spread by itself fairly good.
