Painting the radiator for Satoshi / Grill craft Mod

So, i see many people paint the radiator black when doing a Satoshi or Grillcraft mod. I am thinking of doing this mod bud have a couple of questions on painting the radiator.

1. what paint do you use to paint the radiator? Krylon Hi-Temp? Is there a specific type of radiator paint?

2. Are there any bad effects from painting the radiator?? The radiator "radiates" engine heat, so would the paint somehow interfere with this process?

I guess i am just a bit unsure about the painting the radiator aspect, but definitely want the area behind the new grill to be nice and black.

Thank you for any info.

 

Ok, that sounds good Rustoleum Engine paint...

Nice Grill!

 

Flat black BBQ paint works just fine. Might be a bit cheaper to.
