Mr. Kim, that's what my bries looked like with the slip skin, but mine was mostly around the sides, not so much the top/bottom surfaces. I didn't have that problem with the cams, though, but that may be because I petted them every day, much more around the sides, when I flipped them. Might even go so far as to say I smooshed the sides a little bit patting them down. That seemed to work, 'cause I didn't really have any slips on any of the four sets of cams so far. Besides, I just like saying that I have to go pet the cheese.
As far as regrowth - can you spray some PC on to help them along? Probably worth a shot. I just started spraying my 4th batch, as they got some fairly decent growth at first (have been inoculating the milk, not spraying up to now) but it sort of stalled. Just did one side yesterday, will do second side today, hopefully in a week or so I'll have some better results with that batch. They're already about 2 weeks old, I think.
Anyway - a little rambling, but hope some of it helps anyway.
