Brodak gold dope question

Brodak gold dope question
A fellow C/L model friend is trying to finish his Oriental with Brodak gold dope trim. After testing on some scrap, the gold does not cover well.. and would take a LOT to achieve the results he's looking for. I don't know all the details, but asked via email; if he was thinning the dope... brushing vs. spraying... and if he'd tried using an alternate base-trim color, like light brown or a dark yellow. He hadn't stated what his base color was.. but liked the gold in the photo of my speed model that I sent him. I explained that I didn't use any dope in my finish... but if he can obtain a 1-2oz. bottle of Brodak alternate base-color for his trim "locally".. it might be worth some experimentation.
Any suggestions for helping him "get his gold" without having to apply excessive coats?

Re: Brodak gold dope question
Roddie, I never sprayed gold. I have some here and I have to ask, is this in a bottle or a can. Is this being sprayed? I'm pretty convinced that there are differences between the can and the bottle. It just seems like the material is much thinner in the bottle for brushing purposes. Whenever I have a can of Brodak dope it takes a long time to stir this up. I use a piece of music wire in my cordless drill to mix and it takes a few minutes. I thin it after the solids are thoroughly mixed. I also can't see brushing gold on with good results. Silver has a similar characteristic when brushed and you just don't get a even distribution and it becomes blotchy. I would also think that a sprayed coat of polar gray or white would work as a good undercoat. If silver or gold is thinned too much the solids settle to the bottom requiring constant mixing during the spray period.

Thank You Ken, As I stated; my friend didn't give me much info in his email.. only that it was Brodak gold dope he was trying to use for his trim, and it did not cover well on a scrap piece. I replied asking the questions about thinning and if he was brushing or spraying.. but haven't heard back from him yet. I hope to see him.. as well as Dave Cook, tomorrow or Sunday at the N.E.S.T Spring Memorial Control Line Fly-In at the Wrentham, MA field. I am not at all familiar with Brodak dope, but will tell him of your experience using the bottled vs. canned.. and your method of mixing as well.
Thanks again Ken
