We were in a bind to replace F 900 when the company closed. Cross Check successfully did this. The product sets up slightly slower and the package size is 1 oz so it's not a direct replacement. On the positive note though it carries the same Boeing spec and has a 24 month shelf life. I understand they are also working on a faster setting formula.
