In the past i've used the technique to simulate the gold foil wrapping on the lower stage of a few LEM's and one or two other models but it's Kind of expensive to use Real XXX 23carrot gold leaf on a model rocket. the leafs are about 3" x 3" come 25 leaves to a book, 20 books per pack.
There are at least 3 types of tripleX gold leaf available Surface gild, Glass Gold and Patent gold.
All three have specific trates and uses. For application to the exterior of a model rocket applied by an person how has never worked with leaf before PATENT GOLD is the only leaf you should purchase as it is pre-fixed to the backing leafs making it much easier to handle then loose gild leaf. OH! almost forgot Currently Gold leaf is running about 43-44 dollars PER BOOK.
To apply any of these leaves you'll need a size..sort of a semi-slow to very slow drying varnish. Again for those who haven't worked with leaf I'd strongly suggest the use of SLOW SIZE with you application. it'll take about 6-8 hours to set up to the proper "tack" but will give you a couple hours of working time that medium and fast size would not. You must also remember you'll be overlapping your leaf about at least 1/2" all around. You will be wasting a good third of a sheet for every 5-6 applied.
This helps when trying to decide how much gold, silver or aluminum leaf your going to need.
Size is applied with a brush then allowed to tack before the gold is added. Once the gold is on, it must be burnished down well with a good old cotton balls but the size must be nearly dry at this point...too wet it grabs all the fibres from the cotton, to dry you'll rub right through the gild.
Generally gold leaf doesn't need anything over it. NOT SO On a mod-Roc. you'll want to use a CLEAR overlaying exterior varnish that is GOING TO YELLOW no matter what you do.
If you need more specific instructions or more details just let me know I'll try to help, I'd Strongly suggest looking at one of the many REAL gold leaf vinyls that are currently on the market, They to are very expensive, but are FAR EASIER for the novice to apply. Sorry I don't have more examples to show..they would be mostly Glass gold and surface gilded commerical signs, some really boring stuff... a whole different album LOL!!!
