This is a really good look at how this builder does his work. I get fustrated sometimes at how the videos are put togethter. and I wish I understood the language or if it had subtitles it would be more helpful. But I guess thats just how it goes, I am sure he could'nt understand me either. I am also curious about those Materials, Being used I thought the putty might be the milliput, brand putty as it is advertised to do what he was showing when He formed those casting molds.
