I have an OLD Amaco HF-96 electric kiln that has become rather rusty.
The lid has inset kiln bricks, meaning that they set themselves about 1 =
1/2 inches into the kiln when the lid is shut.
Around the metal frame of both the lid and the kiln body, there is rust. =
Sometimes it chooses to jump into the kiln and ruin the top layer of =
pots (this happening more often then I would like). Being a small kiln I =
can't always put a kiln shelf at the top to prevent this.
What I want to know is.... can I use barbeque paint to paint the lid and =
kiln to stop the rust? I have seen such a beast at my local Canadian =
Tire store and thought it may be able to handle the temperatures. Am I =
right? Or is there something else that would be better.
I fire to cone 6.
Thanks in advance for the help.

Penni:
I don't believe painting over the rust will help much
even if it could stand the temperature rust is like cancer.
You might try "Navel Jelly" sold at hardware stores.
Generally you apply it and let it stand per directions.
Then remove it and the rust with coarse steel wool or whatever.
Hope this helps.

Penni, another product that you could use to get at the deep rust is called
OSPHO. It is similar to Naval Jelly but doesn't need to be washed off. It
turns the rust into a surface that is not very reactive thereby serving as a
wonderful primer base. You can buy it in most automotive paint stores.

I haven't been following this post, but I have tried Rust converter to handle rust
problems and I think it is the easiest and most effective, and you dont have to use
toxic removers. I think there are a few available on the market, but I've used this
one (on rusty metal fences). You can look up how rust converters work, but
basically it bonds and seals. You can paint over that if you want to.

Wow, would my belly button be sore after THAT treatment!! Actually, I don't
let the rust build up in my navel. If did have rust, I might use navAl
jelly to remove it, but not on my body .

Penni asked about painting the exterior of a rusting Amaco kiln. We
used to have 2 of the HF-105's. got a lot of years & firings out of
these beasts. Problem was we only had 208V and Amaco only supplied
240V elements (were supposed to work on 208V) so it took long time to
get to temperature. Lids began to collapse (mostly from students
dropping them) and the metal skin (especially the lid) was rusting
real bad.
Anyway - Penni, yes you can use a high temperature paint on the
exterior metal skin. You have to get rid of the rust first for the
paint to have a good surface to bond to. Use a brass wire wheel that
you attach to a drill to remove the rust.
