Check with Modern Masters (the manufacturer of the rust product in the video). They have a lot of videos on the website and customer service that will help. (by the way, I used a clear coat on patinaed metal and it turned the rust a solid brown, lost all the beautiful variations. So check with this manufacturer and practice before using it yourself.--then of course post your results here so we can all see!)

Hi, Thank you for the Question, we are Photographers at Spacecrafting. We took the photos of this home, however I don't know the answer to your question.

thanks!
