garyt1957 I use Brampton's. What I have now, used last night, is 5/10...full cure in 10 minutes. I was building clubs about a month ago and noticed it was taking a long time to set(leftover) & was a different color. I panicked. Threw it out, opened another tube. Then I noticed I had 15-30. Grabbed the tube from the trash and it was the same. The clubs are playing good. 😉
If the LD fellas trust the quick set* who are we to be naysayers? They will take the club and hit after 10 minutes.
*Not sure what brand they use though.
