Painting radiators and heat pipes

In my experience, you need to really sand off ALL the old paint for the heat-resistant paint to work and not start peeling again.

The best way to fix them is have them sand blasted and have them coated

esteban, you can scrape (hard but doable) all old paint off the radiators, then either poliurethane them, or just rub cooking oil into the clean surface. If you clean them well, the oiled radiator will look antique.

i wonder what combination of heat and cooking oil would do...

Primer--what type of paint do you recommend for painting metal grilles on radiator covers (you know, the kind of perforated sheets you can purchase at a hardware store)? Is there something that won't begin to crack and peel over time?

Bramstar,

I think I would spray them with a heat resistant paint, check with Janovic

Primer--thanks. Was just wondering if you had any you preferred :-)

estaban, let us know what you do and how it comes out...i'm in the same situation as you. I am thinking scraping off the paint (but with a wire attachment for a drill) and if that doesnt work getting them sandblasted.

Nintzk,

Bring them to acme on great jones

jazzobuzzo, "what combination of heat and cooking oil would do..": absolutely nothing. The wrought iron (if that's what we're talking about) is porous and the oil will be absorbed very quickly. It's an old tried and true method, and it works. Believe it or not.

What about the combo of heat, cooking oil, and chopped onions?

Oh, never mind.

Bramstar,
I think Primer refers to Rustoleum ( Krylon brand ) heat resisting paint. You may also consider using engine enamel.
