A bright coloured door can make for a legible entry for visitors. Maybe consider a terracotta rather that bight orange, but hey its your house so go with what you love, can't go wrong !good luck

Yes. Axolotl are amazing! I have sourced a company in Melbourne who pretty much do the same thing. It's Metalcote in Cheltenham. The bronze/graphite sample I have attached to this post is from there. It's liquid metal. Axolotl are in Sydney and the cost of transporting door to and from there, plus cost of coating, is way expensive. Coating alone, minus cost of door, is around $2500+/- I figure for the same product I won't have to pay for return delivery of a heavy door

I think it's the sort of question where it is more efficient since you know the exact product and want some technical details about it, to go to the source, ie the manufacturer, to ask your question. Posting your question on a public forum might or might not get you an answer because there might not be anyone reading who knows the answer. Further, I googled the brand name because I have never heard of it so I wondered if you had posted in the right place. It appears to be a US brand so I am guessing you are in the US and you will find the US Houzz forum more relevant. You can find it here https://www.houzz.com
