Well I am just about out of 2 part and will be in the market to try something new soon. I have been using BRS 2-Part solution for about 4 years now and recently I started having issues with my alk solution turning a greenish yellow in the container mixed. Figured maybe its time to start looking at diffrent stuff. For the time being I mixed up some Baking Soda to create some new alk solution as I was all out but lets hear what you guys all use and what you like and dislike about them.
