I am trying to reinstall my heater. I think I have all the parts that were removed by the PO. I stripped the rust using Evaporust (which worked incredibly well, BTW). Now I need to paint the heat control flaps. Is it okay to paint the inside, or will I send burning fumes into my interior?

I'm planning on using heat-resistant paint. Any recommendations?


Thanks,
Victor

Yes dont use any paint on the inside. I treat the outside once de-rusted then blast & powder coat them.
I assume you checked to ensure the seal material was in good shape prior, otherwise it will still work just not as well.

The inside pads look okay to me. That's why I thought the inside should not be painted.

Thank you!

I used high temp black grill paint.

Is there a way to replace the material inside that creates the seal when they are closed?

@bbrock has done it but i can't find the thread...

Found this:

One of the refurbishing links

That's the one I was thinking of...
