I know there are a lot of threads on this product out there, and I'm not intending to start the debate if Krowtann is an actual tan, but I'm looking for help as I'm having issues with slippage on some (not all) hides when using Krowtann. If/when it happens it's usually around the shoulder or chest area. The hides are all in good condition, and shaved property when they go in. I make sure I follow the label to a "T" however it seems to be crap-shoot on whether slippage occurs or not. The troubleshooting tips on the product suggest over-neutralizing. I've tried to vary time and amount of sodium bicarbonate and does not seem to matter. Any suggestions (other than go to a "true-tan") would be appreciated. Thanks!
