Hi Lauren, That is the 5min version. The deception is that they use the word original.
The one you want is the 'Standard' version. Gives you 80mins+ working time, but requires longer curing time setting-
I've used this brand for over 50 years and in hostile environments in excess temps of 65c and has held fast. There are other brands out there, but have never had a need to try them.
Providing the parts are meticulously clean, dry, sound and abraded for good keyed surfaces, it will do the job.
Regards
