I have an outdoor grill which I want to paint pink. Where can i find
heat resistant (500-800´C), pink paint?

I did some research on your question and what I found is most heat
resistant paint (up to 1000º) is not available in pink.  Perhaps
another researcher can find it for you.

Best regards,

You may need to mix your own, with red and white heat-resistant paint.

It's ok if I have to mix it myself from red and white paint, the
problem is that I have only been able to find heat resistant paint on
a spray-bottle, which makes it hard to mix. If anyone could help me
with red and white, mixable, paint I'd be satisified.

Pinkmachine, I was able to find red paintable, heat resistant paint,
but the only whites I can find are in spray bottles.

Try a product called "Armourguard". Its a water based paint that can
be tinted. I use it on my boat deck and it is the VERY hardest thing
to remove. Problem is, its an industrial product and only comes in
minimum amounts of ten litres. I`m not sure if its available outside
Australia.

Who makes it? The only armourguard I'm able to find makes security
products. Do you have any web-reference?

I think the product pugwashjw mentioned is "ArmorGuard" (note the spelling).

There is some info about it here:
