Why don't these plates come with this prep ready done? - after all we're paying premium for these things. I uses Scotchbrite extensively for metal working and am somewhat confused by the grits/colours to prep the plate. I always thought 000 steel wool was nominally 300 grit and can understand the use of 7447 (red) which is 320 grit but 7446 (dark grey ) is 150 grit and I thought that would be too coarse. Under what circumstance would 7447 be used. Light grey (7448) is 800 grit so it's unlikely you are using that. Thanks for the info.
sorry for any confusion, we had considered pre-scuffing in factory, of course it would have further impact on price, and it is fundamental that the user becomes accustomed to using it for quick cleans between prints, or contaminants will build up and cause catostrophic failure, so we opted to teach the user how to use the scotch Brite and when. We do recommend the 7447 typically, although we show other options incase that specific grain is not available in one's country. If it it very scotch Brite like, the grain is comparable to sand paper grit as far as width of scratches, however the user has more control over amount of material removed by simple pressure alone. hopefully this make sense. thanks!
I actually was about to print on one your PEX plates without this prepwork! Thanks for the info video! It came at the perfect time!
We are glad you found it helpful!
Any thoughts on using a random orbit sander with the scotchbrite for initial prep?
