Has any one had trouble with 1-SHOT metallic gold turning brown in the weather or sun? If so what can I do about it or what is a good alternative.
Thanks

Scot, for my gold needs to be brushed on, I use House of Kolors striping and lettering urethane enamel. You must use the catalyst if no clear coat is to be applied. The catalyst give the gold a gloss finish and troubles go away.

What Joey said!
Even with a clear coat, 1Shot and Kemp Permagild will eventually tarnish!

Three times the charm, what Joey and Si said. Besides 1-shot gold brushes like old mud, but then if you're like me and take it as a challenge to prove it can be done---mix 60 parts 1-shot Gold with 40 parts gloss tinting clear, I've only been doing it this way for 15 years and since I warranty my work for 4 years I think I can say it holds up real well in pinstriping at least. Letterings a whole nother beast---I'm just a pinstriper so got no clue on that end O things

I think any but the real deal (24kt gold) will tarnish, but you might want to try using size and bronze powder. Put the bp in a pounce bag and rub it on when the size reaches the right tack, or dust it on with a soft brush. And use the best clear you can. There are many, many shades of powders around. Maybe there is something in the powdered Mylars?

All the one shot, kemp etc. is bronze powder already mixed into a varnish base. Putting the varnish (size) on first, then bronzing later produces a brighter finish with fewer brush strokes showing. But it tarnishes in the air and humidity because it's metal.So the trick is to seal out the air. A good polyurethane will make it last a pretty good while, depending on conditions (sunlight,weather), but will eventually dull out when the clear coat breaks down enough to expose the bronze to air.
At the fire truck factory where I worked for awhile, I occasionally used various bronze and aluminum powders for special effects, combined with gold. I used Imron straight out of the can with a little activator and NO thinner to clearcoat everything, and it has held up very well. So you see, sealing the air out is the key.
That post about House of Kolors gold sounded good...I got to try that out.
