I’ve heard that you should use differrent materials for a chimney cap depending on the combustion source – i.e. stainless steel vs. galvanized.
I’ve got 2 flues that need caps – one from an oil burning furnace and another for a wood burning fireplace.
Does anyone have any advice?
Skim-coating with joint compound covers texture, renews old drywall and plaster, and leaves smooth surfaces ready to paint.

Typically you're going to buy those parts from the manufacturer of the vent pipe, so they fit together. I have a Metalbestos woodstove chimney that's lined with stainless but has an aluminum cap. Not sure about the oil stove... but again, you want it to fit the pipe you have so buy it from the same manuf.
David,
The flues are masonry/clay pipe.
Won't matter that much. Stainless will supposedly last longer but costs more, and with a decent-quality cap you'll be dead either way before they need replacing.

I see lots of galvanized chimney caps leaving rust stains on the chimney. I think stainless and copper are worth the extra bucks in the long run. If it's a tricky install, the labor will be more expensive than the cap, so do it once with good materials.

Someone told me that galvanized isn't as good as it used to be since the government regulated the lead out of it.
Don't know if that's true, but I rarely see galvanized on a roof that isn't rusting. And it is often just a few years old.
