i know how to paint golden with luster dust and vodka for small pieces..but i want to paint my 8" round cake to compeletly golden color..which gives foil like finish .How should i go about it?

Two options that I know of.

1 Paint it with gold airbrush gel by americolor

2 Apply edible gold leaf (this will cost more but will be way more vivid)

I agree air brush. 

but i suggest you do a coloured undercoat too. when i use silver i apply it on top of mat gray icing 

for gold the undercoat depends on the type of gold affect you are looking for i find that a mustard yellow works well. i have used white and pink too. the trick is to try to imagine the colour without the mettalic finish.

 the advantage to using an undercoat is that it deepens the top coat and means that you dont need as much paint. 

if you don't have an air brush wilton do a spray can http://www.karenscookies.net/Wilton-Color-Mist-Food-Color-Spray--Gold_p_1905.html

this product is available in the UK too

Wow that is going to be so pretty can you post a picture of the finished product?

ADoes anyone Know if you can buy the gold airbrush paint in the UK??

A

Yes you can. Americolor do one available on amazon

AOh thank you :( I will take a look!

AIs this for a client who is expecting a very specific look? You mention foil, and the only way to get that true gilded look of real gold, if indeed that is what you seek, then you'll need to apply gold leaf. Anything else will look different, not bad, but it won't look exactly like metal.

AI found this. Hope it helps. http://cakesdecor.com/vivalacake/blog/426

Ayes the client wants the shiny gold metal look.i have never used gold leaf..is it easy to work with...do u know any tutorial of it?

AGold leaf it is then unless she is made aware of the difference in finish if she opts for a cheaper solution.

Just google silver leaf cake tutorial and you'll find it. There are plenty of resources online for the large gold sheets as well.

Faye Cahill has a tutorial for purchase on her FB page.

Did you find a tutorial on this? I don't own an airbrush, so I've always used Wilton's metalic sprays. They are ok, but it's super easy to get spots that are uneven, and it tends to drip and run. I would love to see what you guys mean by gold leaf. I am not familiar with this. I'll have to give it a search! :)

I found a link to a picture by picture tutorial. She looks like she knows what she's doing. Here it is!

Candmarie, that is a fantastic tutorial  Thanks for posting This site is so awesome for giving help and receiving it.I love to give and I love to receive.

I thought so too! I love this site! 

Ahey thanks...seen the tutorial and it surely helped...am going to give it a try...i don't think its easy to work with with...but i loveee the final effect it gives.

Thanks for sharing my link!  I just used the same technique on a silver leaf cake last week. It's super fast, just be careful not to touch it once your done, the oils from your fingers will ruin it.

Well you are very talented! Do you have pictures of the silver one? We'd love to see!! :)
