Does this epoxy do well in heat? Specifically exhaust/muffler heat?

I used to heat to remove the epoxy when it didn't hold as well as I had hoped. I don't think this would work with a muffler.

What material would be best to mix this on?

I use piece of cardboard. It works, though it’s a pain mixing it. Make sure u mix it well.

will this fill pinholes in welding? I am looking for a product that will easily fill the little pinholes and look (and react) a lot like the steel

Great question. I think it could fill the pinholes, but am unsure if it will look like the steel. You may try painting over with matched color.

Can it be used for a/c aluminum coils repair with 410A refrigerant?

No, It really doesn't work ona lot of items. We tried.
