I use "THESE" in 12 & 30 minute cure times.
Very affordable, especially if you order other things from UMRS to max the benefit of shipping charges.
(You have to look at the quantity on each bottle. Advertised 8oz usually means 2, 4 oz bottles.)
Not just on rockets, but anything that needs fixing around the house.
Only time I've had a failure was a butt joint on plastic handle meat cleaver.
Probably because the wife throws it in the dish washer.
But when it failed, I was putting more stress on it than I should have for being repaired.
Regardless of the external packaging/branding, these are highly likely to be manufactured by Bob Smith Industries (BSI). Just FYI.
