Sorry to hear about this, however, any glossy canvas, non solvent, will need coating. This is especially true if you are using gator/miracle muck. If you need to wipe the canvas off, which I tend to need to, non coated glossy will just wipe right off with any pressure. This is going to be true for any glossy, not just BC brands. On the seeds, I quit using Crystalline earlier this year on any print with large light solids, blue, grey etc, due to the high seed count.
BC's Lyve does not have this issue and BC has their own mill so not sure why their QC on glossy is not holding up better.
You will tend to also see more "blobs" of coating or weave irregularities in the BC glossy canvas line up.
