As per question, door in relatively good condition, just needs a refresh.

How much paint should I buy to make sure I don't run out half way through?

750ml should do a garage door easily.  Though you can always buy a litre if you're heavy handed lol!

Hammerite do a lovely Gold to match your taps!

Paint I'm looking at comes in 500ml tins, so I guess 2 x tins it is.

Now that's sad, never looked at gold in my life. You got a project in mind?? 😁

Being decorating the kids rooms going to do a car feature wall in one off there rooms

Something along this line

The strange bit is the boys have gaming room style what thy wanted. It’s the girls that want a car like graffiti art on there wall lol 😂 girls are more into the cars than the boys 🤣 where did a good wrong lol 😂

It’s the girls that go out in the rs turbo and the st no the boys thy sit and play there game consoles haha 😂 it’s the girls at take to car shows there pure petrol heads lol 😂

Doing a big area like a garage door I wouldn't use normal Hammerite, its too thick. Just use a gloss, satin or enamel. I'd do it with a sponge mini roller and throw it away rather than clean it. If you go the water based route bear in mind some of the low solvent (water based) paints can't be used out doors, just check the one you pick is ok.

 

Quick update. A single 500ml tin of Buckingham Green enamel was more than sufficient, though I probably would have used the whole tin without the black inset frames.
