Sorry but in your video you only scratch the surface for these complex products, e.g. the process does not end after 2h, it will be slower but the rusting continues for 24h and more. If you want to "stop" the process (after 2h and you're fine with the result) cover your model with an enamel varnish. Mig Jimenez has a really good live presentation Video of these products with all important tips and tricks.
