Thanks, Matt I did a belt one time It was a ton of work lots of stitching, and a lot of time washed it after the roon with baking soda way too much soda the belt looked like it was 500 years old it was unusable LOL now. not sure what ph levels I had but thank you for the information if I ever use roon again I'll be sure to check the ph levels for sure I did another job with roon and it didn't crack thank God but I will say I used a lot of water washing it after the roon that was about 4 years ago and it's still fine shit luck on that one if that one had cracked I'm not sure what I would have done. I'll show a pic of that one you will see why I would have left town or something or maybe jumped off a bridge lol.
Doc I let mine sit for about two weeks for the best result don't forget to neutralize the acid as soon as your done with the roon.
