The mixture can be used at any temp, environment will only change the amount of drying time. It is primarily vinegar. Tis' the steel that causes aging. The more you use the more it will age, plus the amount of steel wool or nails, anything that rusts. You will see a change fairly quick. Plus no paint smells, just vinegar and this sets the aging. The nails cause the aging. Will be gray/natural as if in the elements forever.

Of importance though, you can't go back. Also, getting it on anything else, even fabric, will never come out. Once it is aged will stay that way. You can paint over it though. Just slap the mixture on with a brush, like a wash. Be sure to test it on a similar wood. Dark woods like majogany really turn dark, but light ones look gray,aged.

I liked the idea of having a sign over the the door to finish off my shed. It was the look that appealed to me. Have an old one to do this with. You have done a lot of work and love it all.
